When a pendulum is at the position all the way to the left when it is swinging (at the top of the arc), what is true of the kinetic and potential energy?

A.The potential energy is zero, and the kinetic energy is maximized.
B.The kinetic energy is zero, and the potential energy is maximized.
C.Both the kinetic and potential energy are zero.
D.Both the kinetic and potential energy are at their maximum.
E.There is no energy at this position.

The potential energy is zero and the kinetic energy is maximized.
Remember an object in motion has kinetic energy and no potential energy at that particular time.
The potential energy which the object had gets converted into kinetic energy.
I think the problem refers to point A.
what @rvc said applies to point B, the lowest point in the trajectory (and only if we choose the zero for potential energy there).
At point A we can say that the pendulum stops (for an instant), so it is at rest, what do you think would then happen with kinetic energy there?
I said about point A :/
i meant option A
lol i mixed the stuff lol
u r correct @Greg_D
@rvc options A, B and C and points A, B and C in my drawing are not necessarily related! i should have picked better names for the drawing...
Anyway, i hope it is clear now
i got confused with that at first but now it's clear.
