Answer 1

Option “D” is correct that is if they all move in constant acceleration.

• All frames will be inertial if and only if they all move in constant acceleration.

• A-frame would be inertial if it moves with respect to an additional inertial frame with a constant acceleration

• An inertial frame is the one that is either at rest or can move with a constant velocity.
