Assertion : Stress is the internal force per unit area of a body. Reason : Rubber is more elastic than steel.

Options

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

Correct answer

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

Step-by-step solution

Stress is the internal force per unit area of a body. If the same force is applied to the rubber and steel, then strain in rubber is more. It means the rubber is more elastic than steel.
