The correct answer is: B. Wheat.
Kangra and Mandi are two districts in Himachal Pradesh, India. They are the largest and second largest districts in the state, respectively. Kangra is also the most populous district in Himachal Pradesh.
Wheat is the most important foodgrain crop in Himachal Pradesh. It is grown in all the districts of the state, but Kangra and Mandi are the two main wheat-growing districts. In 2019-20, wheat was grown on an area of 1.2 million hectares in Himachal Pradesh, of which 65% was in Kangra and Mandi districts.
The other options are incorrect because:
- Rice is not a major foodgrain crop in Himachal Pradesh. It is grown in a few districts of the state, but its area under cultivation is much smaller than that of wheat.
- Maize is also not a major foodgrain crop in Himachal Pradesh. It is grown in a few districts of the state, but its area under cultivation is much smaller than that of wheat.
- Pulses are a group of crops that include beans, lentils, and peas. They are an important source of protein in the Indian diet. Pulses are grown in all the districts of Himachal Pradesh, but their area under cultivation is much smaller than that of wheat.
