what is the process by which the sun creates energy?\na. gravity\nb. fission\nc. fusion\nd. thermodynamics

Brief Explanations:

The sun creates energy through nuclear fusion. In the sun's core, hydrogen atoms combine to form helium, releasing a vast amount of energy in the process. Gravity is a force and not an energy - creating process for the sun. Fission is the splitting of atoms and is not the process in the sun. Thermodynamics is a branch of physics dealing with heat and energy relationships, not the specific process of the sun's energy creation.

Answer:

C. Fusion
