Answer:
D. Some of the energy went into the ball, and some of it went into the air.
Explanation:
When Jeanie's mallet hit the ball, some of its energy was transferred to the ball, since the ball moved. The loud noise means that some of the energy was changed into sound. Some of the energy stayed in the mallet, because the mallet did not stop moving when it hit the ball. So, some of the energy went into the ball, and some of it went into the air.
