The correct answer is: c) Mokokchung
Mokokchung is a district in the state of Nagaland in north-eastern India. It is the second most populous district in Nagaland after Dimapur. The district is known for its large-scale pineapple cultivation. Pineapple is the main cash crop of the district and is grown in over 10,000 hectares of land. The district produces around 100,000 tonnes of pineapple every year. The pineapples grown in Mokokchung are of high quality and are exported to other parts of India and the world.

- Peren is a district in Nagaland and is not known for its pineapple cultivation.
