A body of mass \( m \) is released from a height \( h \) on a smooth inclined plane that is shown in the figure. The following can be true about the velocity of the block knowing that the wedge is fixed
(a) \( v \) is highest when it just touches the spring
(b) \( v \) is highest when it compresses the spring by some amount
(c) vis highest when the spring comes back to natural position
(d) vis highest at the maximum compression
