Answer:
c) It helps in photoprotection.
Explanation:
Cyclic electron flow in photosynthesis occurs in the thylakoid membrane and involves electrons cycling between photosystem I and the electron transport chain, generating a proton gradient for ATP synthesis. It plays a beneficial role in photoprotection by reducing the formation of reactive oxygen species (ROS) during high light intensity, thus safeguarding photosystems and cellular components from damage.
