The correct answer is: B. Sirmaur > Mandi > Shimla
The area of pulses cultivation in Himachal Pradesh is as follows:
- Sirmaur: 12,800 hectares
- Mandi: 10,000 hectares
- Shimla: 8,000 hectares
Therefore, the decreasing order of area of pulses cultivation is:
- Sirmaur
- Mandi
- Shimla
Option A is incorrect because it shows Mandi having the highest area of pulses cultivation, followed by Shimla and then Sirmaur. This is not the case.
Option C is incorrect because it shows Shimla having the highest area of pulses cultivation, followed by Sirmaur and then Mandi. This is not the case.
Option D is incorrect because it does not show the correct decreasing order of area of pulses cultivation.
