<em>The correct option is D) The energy of the car will decrease, and the energy of the block will increase. </em>
Explanation:
As we know energy cannot be created or destroyed but it can change from one form to another. When the wooden car will collide with the wooden block, some of the kinetic energy with which the car was moving will be passed to the wooden block. As a result, the wooden block will also get pushed along the track. Meanwhile, as the wooden car had transferred some of its energy, its energy level will decrease and it will move slower than before pushing the wooden block along with it.
