The correct answer is (c) Tea.
Tea is an ideal crop to grow in an area with annual rainfall of more than 200 cms and sloping hills because it is a perennial crop that can tolerate high rainfall and shade. It is also a high-value crop that can be grown on a small scale.
Jute is an annual crop that is not as tolerant of high rainfall as tea. It is also a low-value crop that is not as profitable to grow.
Cotton is a thirsty crop that requires a lot of water. It is not ideal to grow in an area with high rainfall, as this can lead to waterlogging and soil erosion.
Maize is a cereal crop that is not as tolerant of shade as tea. It is also a low-value crop that is not as profitable to grow.
In conclusion, tea is the ideal crop to grow in an area with annual rainfall of more than 200 cms and sloping hills. It is a perennial crop that can tolerate high rainfall and shade, and it is a high-value crop that can be grown on a small scale.
