Which of the following statements about the origin of India's island groups is correct? I. The Andaman and Nicobar Islands are of coral origin. II. The Lakshadweep Islands are of coral origin.

The correct answer is A, Little Andaman and Car Nicobar. The Ten Degree Channel runs along the tenth parallel of north latitude and is the dividing line between the Andaman group and the Nicobar group; Little Andaman is the southernmost island of the Andaman group and Car Nicobar the northernmost of the Nicobar group, so the channel lies between them. Option B is wrong because North Andaman and Middle Andaman are not divided by a named channel at all; together with South Andaman they form the single landmass called Great Andaman. Option C is wrong because the water between Great Nicobar and Sumatra is the Great Channel, also called the Six Degree Channel, which is India's maritime boundary with Indonesia. Option D is wrong because Minicoy is separated from the Maldives by the Eight Degree Channel, and from the rest of Lakshadweep by the Nine Degree Channel.

The correct answer is B, Indira Point. Indira Point stands at the southern end of Great Nicobar in the Nicobar group and is the southernmost point of the territory of India; it was known earlier as Pygmalion Point and as Parson Point. Option A is wrong because Kanyakumari is only the southernmost point of the Indian mainland, not of Indian territory, and students lose the mark by confusing the two phrasings. Option C is wrong because Minicoy is the southernmost island of Lakshadweep in the Arabian Sea, which lies well to the north of Indira Point. Option D is wrong because Point Calimere, or Kodikkarai, is a headland on the Tamil Nadu coast in the Palk Strait area, known for its bird sanctuary, and is nowhere near the southern limit of Indian territory.

The correct answer is B, Barren Island. Barren Island lies in the Andaman Sea to the east of Middle Andaman and carries the only active volcano in India and in South Asia; it has erupted several times in recent decades. Option A is wrong because Narcondam Island, also volcanic and also east of Great Andaman, carries a dormant volcano, and is remembered instead as the only home of the Narcondam hornbill. Option C is wrong because North Sentinel Island is known for the Sentinelese, an uncontacted tribal community, and has no volcano. Option D is wrong because Baratang, between Middle and South Andaman, has mud volcanoes and limestone caves; a mud volcano is a vent of gas and slurry and is not a volcano in the igneous sense, which makes it a favourite distractor.

The correct answer is C, North Andaman. Saddle Peak rises to about 732 metres in North Andaman and is the highest point of the whole union territory; a national park of the same name surrounds it. Option A is wrong because the highest point of Great Nicobar, and of the Nicobar group, is Mount Thullier at about 642 metres, which is a common pairing in matching questions. Option B is wrong because South Andaman carries Port Blair and Mount Harriet, now called Mount Manipur, which is much lower than Saddle Peak. Option D is wrong because Little Andaman, lying south of the Duncan Passage, is low and flat compared with the northern islands. Remember the pair Saddle Peak with North Andaman and Mount Thullier with Great Nicobar.

The correct answer is A, Kavaratti. Kavaratti is the administrative headquarters of Lakshadweep and the seat of its administrator. Option B is wrong because Androth, though the largest island of the territory by area and the one nearest the mainland, is not the capital. Option C is wrong because Agatti is remembered for carrying the only airport of Lakshadweep, which makes it the island most aspirants wrongly promote to capital. Option D is wrong because Minicoy is the southernmost island of the group, separated from the rest by the Nine Degree Channel and distinguished by the Mahl language written in the Thaana script. Keep three pairs apart for this territory: Kavaratti the capital, Androth the largest, Agatti the airport. Lakshadweep, with an area of only about 32 square kilometres, is the smallest union territory of India, and its ten inhabited islands are administered from Kavaratti by an administrator appointed by the President.
