(b) False

I got this question during an interview for a job.

Answer 1

The correct option is (a) True

For explanation I would say: Every simple harmonic motion is periodic motion, but every periodic motion need not be simple harmonic motion. For example, when the motion of the earth around the sun is a periodic motion, but not simple harmonic motion as the back and forth motion is not taking place.
