Options

A. Is an inertial frame by definition
B. Cannot be an inertial frame because earth is revolving round the sun
C. Is an inertial frame because Newton’s laws are applicable
D. Is an inertial frame because the earth is rotating about its own axis

Answer

Explanation

The frame of reference which are at rest or in uniform motion are called inertial frames while frames which are accelerated with respect to each other are non-inertial frames. Spinning or rotating frames are accelerated frames, hence these are non-inertial frames.
