action and reaction are equal in magnitude and opposite in direction. Then why do they not balance each other.

Explanation:

Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
