Why Correct: Sikkim consistently reports the highest per capita forest area among Indian states, with approximately 0.8-0.9 hectares per person, due to extensive forest cover exceeding 47% of its area and a small population under 700,000.
Distractor Analysis: Madhya Pradesh has the largest total forest area but a population over 80 million reduces per capita availability to about 0.2 hectares. Assam has forest cover around 35% but high population density yields per capita figures below 0.2 hectares. Jammu & Kashmir has substantial forest resources but per capita availability remains lower than Sikkim's despite recent demographic changes.
Takeaway: Arunachal Pradesh typically ranks second in per capita forest area, while densely populated states like Bihar and Uttar Pradesh have the lowest figures, often below 0.05 hectares per person.

Why Correct: Mangrove forests, such as those in the Sunderbans, have exceptionally high carbon storage per hectare because they accumulate large amounts of biomass in both above-ground vegetation and below-ground sediments. Their waterlogged, anaerobic soils slow decomposition, locking carbon into the soil for long periods. This makes them among the most carbon-dense forests on Earth, exceeding typical terrestrial forests on a per-hectare basis.
Distractor Analysis: Srinagar Sal forest is a tropical dry deciduous forest with moderate biomass and lower carbon density than mangroves. Medicinal moist deciduous forest in Buxa Tiger Reserve has higher productivity than dry deciduous but still less carbon storage than mangroves. Evergreen temperate forest in Lava, Kalimpong, though dense, has lower carbon storage per hectare than tropical mangroves because of cooler temperatures and slower biomass accumulation.
Takeaway: Mangroves store 3–5 times more carbon per hectare than tropical terrestrial forests, a phenomenon known as "blue carbon". India's Sunderbans, the largest mangrove forest in the world, plays a critical role in carbon sequestration.
