Assertion: No real body is truly rigid.
Reason: A rigid body is a body with a perfectly definite and unchanging shape. The distances between different pairs of particles of such a body do not change.

Options

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 but reason is false.
D. If both assertion and reason are false.

Answer

A

Explanation

It is evident from the second statement that no real body is truly rigid, since real bodies deform under the influence of forces. But in many situations the deformations are negligible.
