Group of answer choices

D

C

A

B

Answer 1

I can’t see the figure you mentioned. Potential energy (gravitational) is U = mgh, so for identical balls the one at the greatest height above the reference level has the largest potential energy. If you tell me which letter (A, B, C, or D) is at the highest position in the diagram or reattach the image, I’ll pick the correct letter.
