The correct answer is

Electric energy

Kilowatt-hour (kWh) is the product of power (kilowatt) and time (hour), and power multiplied by time gives energy.

Therefore, kWh is a unit of energy, specifically used to measure electric energy consumption or generation, such as solar energy output.

Current is measured in amperes, electric charge in coulombs, and force in newtons, none of which correspond to kWh.

Hence, the physical quantity corresponding to kWh is electric energy.
