Which of the following is not a Harappan site?

The correct answer is D, Diwan-i-insha. The Diwan-i-insha was the department of royal correspondence in the Delhi Sultanate. It drafted the Sultan's letters and orders to provincial governors and other rulers, kept copies of them and was headed by the Dabir-i-khas, who had to be a careful writer of Persian because the wording of a farman carried the Sultan's authority. Option A is wrong because the Diwan-i-arz was the military department, under the Ariz-i-mumalik, which recruited soldiers, paid them and held the horse-branding and descriptive roll system. Option B is wrong because the Diwan-i-khairat was the department of charity, set up by Firoz Shah Tughlaq to give help to the poor and to arrange marriages of poor girls. Option C is wrong because the Diwan-i-risalat looked after religious matters and grants to scholars. Exam tip: insha for letters, arz for the army, wizarat for finance.

The correct answer is C, Ghiyas ud din Balban. Balban, who ruled from 1266 to 1287, brought the Persian court customs of sijda, bowing low before the Sultan, and paibos, kissing his feet, into the Delhi court. They went with his idea of kingship, in which the Sultan was Zill-i-Ilahi, the shadow of God on earth, a person set far above his nobles. He also celebrated the Persian festival of Nauroz, broke the power of the group of forty nobles known as the Chalisa, and used a policy of blood and iron against rebels. Option A is wrong because Muhammad bin Tughlaq is remembered for token currency and the shift of the capital to Daulatabad. Option B is wrong because Nasir-ud-din Mahmud was the mild ruler under whom Balban held real power as naib. Option D is wrong because Qutb-ud-din Aibak founded the Slave dynasty and was called Lakh Baksh. Exam tip: Balban - sijda, paibos, Nauroz and Zill-i-Ilahi.

The correct answer is D, Ashwini Kumar Dutta. He founded the Swadesh Bandhab Samiti at Barisal in 1905, during the movement against the partition of Bengal. The samiti built a network of village volunteers who pushed swadeshi goods, enforced the boycott of foreign cloth, settled local disputes through their own arbitration courts and organised relief work, which made it the strongest of the Swadeshi era volunteer bodies. A teacher by calling, Dutta had earlier set up Brajamohan College in Barisal, and the government banned the samiti and deported him in 1908. Option A is wrong because Chandrasekhar Azad led the Hindustan Socialist Republican Association and died at Alfred Park, Allahabad, in 1931. Option B is wrong because Bhagat Singh worked through the Naujawan Bharat Sabha and the HSRA. Option C is wrong because Rajguru was an HSRA member hanged with Bhagat Singh and Sukhdev in 1931. Exam tip: Swadeshi volunteer bodies - Swadesh Bandhab Samiti of Barisal and Anushilan Samiti of Bengal.

The correct answer is C, Anga. Champa was the capital of the Anga mahajanapada, and its site lies near modern Bhagalpur in Bihar, where the Champa river meets the Ganga. Anga is one of the sixteen mahajanapadas listed in the Buddhist text Anguttara Nikaya, and Champa was among the six great cities of the Buddha's time. The kingdom was rich because the river port carried trade downstream, which is why Bimbisara of Magadha annexed it and made his son Ajatashatru its governor. Option A is wrong because the capital of Kashi was Varanasi. Option B is wrong because Matsya, in the Alwar-Jaipur region of Rajasthan, had Viratnagar as its capital. Option D is wrong because the Vajji confederacy, a group of clans led by the Lichchhavis, had its centre at Vaishali. Exam tip: pair the capitals - Anga-Champa, Kashi-Varanasi, Vajji-Vaishali, Magadha-Rajgir.

The correct answer is C, Ramanuja. Ramanuja, born at Sriperumbudur in Tamil Nadu in the eleventh century, taught Vishishtadvaita, or qualified non-dualism. He held that the soul, even when it becomes one with the supreme God Vishnu, keeps its own separate existence, and that the surest way to salvation is intense devotion, bhakti, to Vishnu. Deeply influenced by the Alvar saints, he opened temple worship and devotion to people of every caste, and his ideas later inspired Ramananda and the Bhakti saints of the north. B is wrong because Shankara, of eighth century Kerala, taught Advaita, pure non-dualism, in which Brahman alone is real and the world is maya. A and D are wrong because Allama Prabhu and Basavanna belonged to the Virashaiva or Lingayat movement of Karnataka, which worshipped Shiva in the form of the linga and rejected caste and ritual rather than framing this school. Exam tip: Shankara for Advaita, Ramanuja for Vishishtadvaita and Madhvacharya for Dvaita.
