C Correct answer
Explanation

Stars generate energy through nuclear fusion, where lighter nuclei (primarily hydrogen) combine to form heavier nuclei (helium) in the star's core. This process releases enormous amounts of energy because the mass of the products is slightly less than the mass of the reactants - this 'missing' mass is converted to energy according to E=mc². Nuclear fission (splitting heavy nuclei) is not the primary energy source for stars.
