Solution

The correct option is C Assertion is correct but Reason is incorrect
“Every body continues to be in its state of rest or of uniform motion in a straight line unless compelled by an unbalanced external force.” It is simply expressed as if the net external force on a body is zero, its acceleration is zero. Acceleration can be non-zero only if there is a net external force on the body.
so assertion is correct but reason is incorrect
