B. Hydrogen nuclei fuse, forming helium and releasing energy.

In the Sun’s core, hydrogen nuclei undergo nuclear fusion (primarily the proton–proton chain), converting mass to energy (E = mc^2) and producing the photons we see as sunlight. The other choices describe chemical reactions (iron + oxygen, oxygen + carbon) or photosynthesis (light + water → glucose), which are not the Sun’s energy source.
