The correct answer is: a) Rice
Rice is the most important crop in Arunachal Pradesh, accounting for over 80% of the state’s cultivated area. It is grown in both the hilly and the plain areas of the state. The main rice-growing areas are the Brahmaputra valley, the Subansiri valley, and the Lohit valley.
Rice is a tropical crop that requires a warm and humid climate. The ideal temperature for rice cultivation is 25-30 degrees Celsius. The crop also requires a lot of water, and is usually grown in flooded fields.
Rice is a major source of food for the people of Arunachal Pradesh. It is also used to make a variety of other products, such as rice flour, rice wine, and rice paper.
The other options are incorrect because:
- Wheat is a temperate crop that does not grow well in the tropical climate of Arunachal Pradesh.
- Maize is a drought-tolerant crop that is not as well-suited to the humid climate of Arunachal Pradesh.
- Tea is a plantation crop that is grown in specific areas of the state, and is not as widely cultivated as rice.
