Joule is the SI unit of energy.

Explanation:
Energy in the SI system is measured in joules. A joule is defined as the amount of work done when a force of one newton moves an object one meter in the direction of the force, linking energy directly to work. Because force is measured in newtons and temperature in kelvins, the statement that a joule is the SI unit of energy is exact. The other options point to different quantities: a unit of force (newton) and a unit of temperature (kelvin), not energy, so they don’t fit.
