Vibration of an object about an equilibrium point is called simple harmonic motion when the restoring force is
proportional to:
a. a spring constant. b. displacement. c. time. d. mass

Displacement

Explanation:

An object exhibiting simple harmonic motion, the restoring force is directly proportional to the displacement of the object. The direction of direction of the force is in opposite direction of the displacement. It is given by :

k is the spring or force constant

x is the displacement

So, the correct option is (b) "displacement".
