Vedclass · Answer

(B) Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law is valid only in inertial reference frames,which are frames of reference that are not accelerating. In non-inertial reference frames,pseudo-forces appear,and the law does not hold in its standard form. Therefore,the correct option is $B$.
