A student kicks a soccer ball in a high arc toward the opponent's goal. At the highest point in its trajectory:
A) both velocity and acceleration of the soccer ball are zero.

At the highest point, the vertical component of the velocity is zero, but the horizontal component is not, so the velocity is not zero. The acceleration due to gravity is always acting downwards, so it is not zero.
