Assertion: Snow does not melt eaasily at mountains.
Reason: A decrease in pressure leads to an increase in freezing point.

A

If both assertion and reason are true and the reason is the true explanation of the assertion.

B

If both the assertion and reason are true but the reason is not the correst explanation of assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
