The correct answer is: a) Rayalaseema region.
Rayalaseema is a region in the southern Indian state of Andhra Pradesh. It is one of the three geographical divisions of the state, along with Coastal Andhra and Telangana. The region is known for its dry climate and erratic rainfall patterns. This makes it a challenging place to grow crops, and farmers in the region often face droughts and crop failures.
The other options are incorrect because:
- Coastal districts are not as dry as Rayalaseema and receive more rainfall.
- Hilly areas receive more rainfall than Rayalaseema and are not as prone to droughts.
- Areas with canal irrigation are not as dry as Rayalaseema and have a more reliable source of water.
In conclusion, the correct answer to the question “Droughts and erratic rainfall patterns are a challenge for agriculture in: a) Rayalaseema region b) Coastal districts c) Hilly areas d) Areas with canal irrigation” is a) Rayalaseema region.
