# Select the correct option based on statements below: Assertion (A): Newton's law of action and reaction is a consequence of Newton's law of inertia. Reason (R): Newton's law of inertia implies that any body that is not acted upon by external forces cannot change its state of rest or uniform motion.   1. (A) is true but (R) is false. 2. (A) is false but (R) is true. 3. Both (A) and (R) are true and (R) is the correct explanation of (A). 4. Both (A) and (R) are true but (R) is not the correct explanation of (A).

Given below are two statements:
 Assertion (A): A standing bus suddenly accelerates. If there was no friction between the feet of a passenger and the floor of the bus, the passenger would move back. Reason (R): In the absence of friction, the floor of the bus would slip forward under the feet of the passenger.
