Assertion. A bubble comes from the bottom of a lake to the top.
Reason. Its radius increases.

A

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

B

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

C

If assertion is true and reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
