Answer: a
Explanation: Newton's First Law (inertia) states an object at rest stays at rest and an object in motion stays in motion at constant velocity unless acted on by a net external force — the stationary book must have a force applied (picked up or pushed) to make it move.
(b) is Third Law (action–reaction). (c) and (d) illustrate the Second Law (a = F/m).
