Answer:

The answer is D. At the top of the swing where it briefly stops before changing direction.

Explanation:

When the pendulum is either at its far right or left position, the bob is at rest and therefore its kinetic energy is equal to zero- making it the lowest point of kinetic energy during the whole process.
