A. the conversion of mass into energy during nuclear fusion
Nuclear fusion in a star’s core converts a tiny amount of mass to energy (E = mc^2), releasing heat that raises the thermal energy (temperature) of the stellar gas. Temperature determines the star’s spectrum and color (hotter stars peak at shorter/bluer wavelengths). The other options are incorrect: magnetic fields don’t “destroy” matter to heat the star, stars are ionized plasmas not melting fuel, and chemical reactions can’t produce the huge energies or mass–energy conversion that fusion does.
