The Sikkim Organic Mission plays a role in:

Promoting and implementing organic practices
Banning traditional farming methods
Centralizing control of agricultural land
Discouraging exports of organic produce

The correct answer is: a) Promoting and implementing organic practices.

The Sikkim Organic Mission is a government initiative that aims to make Sikkim the world’s first organic state. The mission promotes and implements organic practices, such as using natural fertilizers and pesticides, and rotating crops. It also provides training and support to farmers who are transitioning to organic farming.

Option b) is incorrect because the mission does not ban traditional farming methods. In fact, it encourages farmers to use traditional methods that are compatible with organic farming.

Option c) is incorrect because the mission does not centralize control of agricultural land. Instead, it works with farmers to help them transition to organic farming on their own land.

Option d) is incorrect because the mission encourages the export of organic produce. In fact, it has helped to increase the demand for Sikkim’s organic produce both within India and abroad.
