The book 'The Light We Carry: Overcoming in Uncertain Times' was written by:

The correct answer is C, Pankaj Mishra. Pankaj Mishra is an Indian essayist and novelist who writes on politics, history and ideas, and The World After Gaza is his book on how the conflict in West Asia is read differently in the West and in the formerly colonised world. His better known earlier works are Age of Anger and From the Ruins of Empire. Option A is wrong because S. Jaishankar, the External Affairs Minister, wrote The India Way and Why Bharat Matters, both on India's foreign policy. Option B is wrong because Aishwarya Pandit is a historian of modern India and did not write this title. Option D is wrong because Amitabh Kant, a former chief executive of NITI Aayog, writes on development and administration, including Made in India. When such a question offers three Indian writers of non-fiction, match the subject of the book to the writer's usual field.

The correct answer is C, Dr. V I Mathan. The book tells the story of the Christian Medical College at Vellore, one of India's oldest teaching hospitals, and it was written by Dr. V I Mathan, a physician long associated with that institution. Option A is wrong because Romila Thapar is a historian of ancient India whose books include Early India and Asoka and the Decline of the Mauryas, not institutional histories of hospitals. Option B is wrong because Atul Gawande is an American surgeon and writer known for Being Mortal, Complications and The Checklist Manifesto. Option D is wrong because Devi Shetty is the cardiac surgeon who founded the Narayana Health chain and is in the news for low-cost surgery, not as the author of this book. In questions about an institution's history, the author is usually a person from that institution.

The correct answer is A, S. Jaishankar. Subrahmanyam Jaishankar, India's External Affairs Minister and earlier the Foreign Secretary, wrote Why Bharat Matters, in which he explains India's place in a changing world order; his earlier book, published in 2020, is The India Way: Strategies for an Uncertain World. Option B is wrong because Shashi Tharoor's recent titles are Ambedkar: A Life and Pride, Prejudice and Punditry, and his best known book on colonial rule is An Era of Darkness. Option C is wrong because Nirmala Sitharaman, the Finance Minister, is not the author of this book. Option D is wrong because Jairam Ramesh writes political biography and environmental history, including Indira Gandhi: A Life in Nature. Both books by Jaishankar are frequently asked, so learn the pair together. Note also that the option list here is made of four Indian public figures who have all written books.

The correct answer is C, Raghuram Rajan. Raghuram Rajan, who was Governor of the Reserve Bank of India from 2013 to 2016, wrote Breaking the Mould with the economist Rohit Lamba, arguing that India should build on services and skills rather than copy the manufacturing path of East Asia. Option A is wrong because D. Subbarao, Governor before Rajan, wrote Who Moved My Interest Rate and Just A Mercenary. Option B is wrong because Urjit Patel, Governor after Rajan, wrote Overdraft: Saving the Indian Saver. Option D is wrong because Y. V. Reddy wrote Advice and Dissent: My Life in Public Service. All four Governors have written books, which is exactly why the options look alike, so fix each title with its author rather than remembering the list of Governors alone.

The correct answer is A, Geetanjali Shree. Her Hindi novel Ret Samadhi, translated into English by Daisy Rockwell as Tomb of Sand, won the International Booker Prize in 2022 and became the first book originally written in any Indian language to do so; the prize money is shared equally by the author and the translator. Option B is wrong because Mamta Kalia is a Hindi novelist and poet, but she has not won this prize. Option C is wrong because Krishna Sobti, the author of Mitro Marjani and Zindaginama, won the Jnanpith Award in 2017 and died in 2019, before this prize was given. Option D is wrong because Mridula Garg, who wrote Chittacobra and Miljul Mann, is a Sahitya Akademi awardee rather than a Booker winner. Note the difference between the two Booker prizes: one is for fiction in English, the other for a translation.
