D when it was sitting of the shelf

Answer:

B) Just before it strikes the ground.

Explanation:

The kinetic energy of the book is the highest right before it hits the ground because all of the stored potential energy the book had on the shelf is converted to kinetic energy right at the bottom of the shelf (but before it hits the ground, otherwise, the KE would be 0 because the book would have zero velocity).
