The correct answer is option-1 Mizoram. Mizoram has the largest forest area in proportion to its total land area compared to the other states mentioned in the options.
Mizoram is located in the northeastern part of India and is known for its rich and dense forests. It is home to several national parks and wildlife sanctuaries, contributing to its large forest cover. These forests are not only important for maintaining ecological balance but also serve as a habitat for various flora and fauna, including some endangered species.
While the other states mentioned in the options, namely Arunachal Pradesh, Sikkim, and Jammu and Kashmir, also have significant forest areas, Mizoram has the largest forest cover in relation to its total land area.
It is worth noting that forest cover is crucial for maintaining biodiversity, preventing soil erosion, and mitigating climate change by absorbing carbon dioxide from the atmosphere.
