    The definition of C.O.R is the ratio of impulse of the restoring force to the impulse of the deforming force. So your closest answer is B momentum.

    Since C.O.R. is a ratio of KE, the single best answer is A) but E) might be considered because height is a direct result of KE converted to GPE.
