The object with potential energy from the given choices is the can of gasoline. This is because potential energy is stored energy based on an object's position or state. The gasoline has chemical potential energy stored within it, which can be released when it is burned.
The rock on the ground can also be said to have potential energy if it's at a height above a reference point (like the ground level), but since it is specified as on the ground, its potential energy is minimal compared to an elevated position.
The unlit lightbulb and stereo speaker do not possess significant potential energy in the context of stored energy related to position or state.
