Answer: It is a leaf hanging on a tree
Explanation:
Gravitational Potential Energy (GPE) is energy that is stored and ready to be transformed to kinetic energy when it becomes in motion.
A light bulb has heat and light energy, so it can't be that
A mouse eating cheese is the mouse taking in chemical energy, so no
A car sitting in the driveway has chemical potential energy because it cant move unless the ignition transforms into kinetic energy.
So the only option left is a leaf hanging on a tree.
