Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: Drainage increases the soil temperature.
Reason R: Drainage decreases the heat capacity.
In light of the above statements, choose the most appropriate answer:

Correct option is A

Drainage improves soil aeration, reducing waterlogged conditions, which allows faster heating of soil due to lower heat capacity. Since water has a high heat capacity, its removal (via drainage) decreases the soil's heat capacity, resulting in increased temperature.
