Answer:

Option C

Explanation:

Let the potential energy of rock A be represented as Pa

And the potential energy of rock B be represented as Pb

Pa = ma * g * h

Pb = mb * g*h

ma = 2 * mb

Thus, Pa = 2 mb * g*h

Pa/Pb = 2 mb * g*h/mb * g*h

Pa/Pb = 2

Pa = 2 * Pb

The energy pf rock A is two times the energy of rock B.

OR

Pb = Pa/2

Hence, option C is correct
