Assertion : A water drop sticks to the glass surface. Reason : Water have properties of surface tension.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

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

Step-by-step solution

A water drop sticks to the glass surface because contact angle between water of glass is acute due to surface tension.
