Heavier and higher add to potential energy because more energy is available to be released when it falls.
That makes it the large rock atop a large hill as the answer.

I think its peach. As both rocks are sitting on steep hills and they have to deal /and actually they are, with friction and gravity at same time. While peach is hanging on the tree is free from friction and , the gravity is actually helping it to increase it potential energy. On the top of this it is hanging with a tiny and not that strong support.
Please let me know if you know the exact anwer. thanks

the potential energy is called Kinetic energy in pgysics
from the choices given the 1 ton rock at the top of the steep hill has
the most kinetic energy according to Newton's laws of gravity

the large rock of course
it weighs more and it can travel down the hill gaining speed and energy as it keeps going down the hill...........
unless the peach hits you on the head as your sitting under the tree..then that's the one I would pick...
good luck

Think of the chemistry of the Peach.

the 1 tonne rock. It will have the most energy when it actually moves.

large rock

the one tonne rock will have the most potential gravitational energy (GPE) as described by GPE=mass*acceleration due to gravity* height.

I agree with livermore, you need a force to make it fall.
