Reason The gravitational force on insect is balanced by force due to surface tension.

• A. Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Assertion is incorrect but Reason is correct.

Answer: (A)

Sometimes insects can walk on the surface of water due to surface tension, when legs of insects are not being wet.
In this situation, the gravitational force on insect is balanced by force due to surface tension.
Therefore, Assertion and Reason are correct and Reason is the correct explanation of Assertion.
