For a pendulum, when is the kinetic energy (KE) greatest and the gravitational potential energy (GPE) least? ?

The answer is A because when the pendulum is at the bottom of the swing, it has no potential energy from gravity (it cant fall anymore) if you look at the other answer choices, they are all describing potential energy (when the pendulum is not actually moving but is ready to fall downwards)
