B Correct answer
Explanation

Chlorophyll carries out 3 types of reactions during photosynthesis: 1) Photoionization (chlorophyll absorbs light and loses an electron), 2) Electron transport (passing excited electrons through the electron transport chain), and 3) Photophosphorylation (ATP synthesis using the proton gradient created). These are the light-dependent reactions.
