Solution

The correct option is C Passes electrons to Photosystem I
Photosystem II is the first protein complex in the light-dependent reactions of photosynthesis. It has P680 at its reaction center.
Photosystem II captures photons of light to energize electrons that are transferred through a variety of coenzymes and cofactors to Photosystem I.
The energized electrons are replaced by oxidizing water to form hydrogen ions and molecular oxygen. The hydrogen ions (protons) thus generated help create a proton gradient that is used by ATP synthase to generate ATP.
