The correct answer is explained below:
- Assertion is correct but the reason is not correct.
- The low-pressure conditions over northwestern India moved to the Bay of Bengal by early November.
- This shift leads to cyclonic depressions over the Andaman Sea.
- These cyclones usually cross the eastern coasts of India and cause heavy and widespread rain.
- The bulk of the rainfall of the Coromandel Coast is derived from depressions and cyclones.
- Parts of western coast and northeastern India receive over about 400 cm of rainfall annually.
- The north-east monsoon winds that pick up moisture from the Bay of Bengal are blocked by these mountains.
- Therefore, because of the obstruction created by the Eastern Ghats to these winds, the Coromandel coast receives rainfall during the winter season.
