In the study of cosmology, "Baryogenesis" refers to:
a) The theoretical processes that occurred in the early universe to produce an excess of baryons (protons and neutrons) over antibaryons, leading to the matter-dominated universe we observe today.
b) The formation of baryonic matter from primordial elements.
c) The interaction of baryons with dark matter.
d) The cooling of the universe after the Big Bang.
