A man pulls a block heavier than himself with a light rope. The coefficient of friction is the same between the man and the ground, and between the block and the ground
(a) The block will not move unless the man also moves
(b) The man can move even when the block is stationary
(c) If both move, the acceleration of the man is greater than the acceleration of the block
(d) None of the above assertions is correct
