The block which is moving with constant speed 4 m/s with respect to ground is observed from two reference frames A and B. The frame A is non-inertial while B is inertial, then

A)  acceleration of block, with respect to A as well as with respect to B is zero

B)  acceleration of block, with respect to A is non-zero while with respect to B is zero

C)  acceleration of block with respect to A may be zero while with respect to B may be non-zero

D)  acceleration of block with respect to both reference frames A and B would be non-zero
