Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : A person jumping out of the moving bus falls forward because his feet suddenly come to rest, while his body is in motion with the bus.
Reason (R) : This is based on Newton's Second law of motions, which states that a body continues to be in it's state of rest or of uniform motion in a straight line unless compelled by an external force to change that state.
In the light of the above statements, choose the most appropriate answer from the options given below :

Solution
Assertion is correct - it describes inertia. But the law described in the Reason is Newton's First Law (law of inertia), not the Second Law. So R is incorrect. Hence (A) is correct but (R) is not correct.
