II.It is referred to as 'slash and burn' technique
III.In it, the fertility is exhausted in a few years
Answer: A
All three statements are true.
Jhum is the shifting cultivation of the north-east, practised in Assam and the neighbouring hill states. A forest patch is cleared and burnt - hence 'slash and burn' - and the ash fertilises the soil, but that fertility is exhausted in two or three years and the plot is abandoned.

Which is the largest state of India by area?
Answer: D
Correct answer: Rajasthan
Rajasthan is the largest state by area, about 342,000 square kilometres - roughly a tenth of India. Madhya Pradesh is second, Maharashtra third and Uttar Pradesh fourth. Rajasthan became the largest in 2000, when Madhya Pradesh was divided and Chhattisgarh created out of it. Much of it is arid: the Thar Desert occupies its western half, and the Aravalli range runs diagonally across it, separating the desert from the more fertile southeast. The Aravallis are among the oldest fold mountains in the world and act as a barrier that has kept the desert from advancing towards the Gangetic plain. By population the order is quite different, with Uttar Pradesh far the largest, followed by Maharashtra, Bihar and West Bengal. The smallest state by area is Goa, and the smallest by population is Sikkim.

Which state has the longest coastline in India?
Answer: C
Correct answer: Gujarat
Gujarat has the longest coastline of any Indian state, roughly 1,600 km, owing to the deeply indented Gulf of Khambhat and Gulf of Kutch and the Saurashtra peninsula between them. That coast gives it a leading position in maritime trade, ports, fishing and salt production, and Kandla was India’s first special economic zone. Andhra Pradesh has the second longest, and Tamil Nadu the third. India’s total coastline, including the island territories, is about 7,500 km. Among union territories the Andaman and Nicobar Islands have a longer coastline than any mainland state, since a scattered archipelago has a great deal of shore for its area - a reminder that coastline length depends heavily on how finely the measurement follows the indentations. The nine coastal states are Gujarat, Maharashtra, Goa, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh, Odisha and West Bengal.
