BPhotosystem II on the thylakoid lumen side
CPhotosystem I on the thylakoid stroma side
DCytochrome b6f complex in the membrane
Answer & Solution
Correct answer: B. Photosystem II on the thylakoid lumen side
The water-splitting complex (oxygen-evolving complex) is associated with PS II, located on the inner (lumen) side of the thylakoid.
Protons released stay in the lumen, contributing to the proton gradient.
