The primary electron acceptor in cyclic photophosphorylation is:

Explanation

c) NADP:NADP (nicotinamide adenine dinucleotide phosphate) is the correct answer. In cyclic photophosphorylation, the primary electron acceptor is a molecule of NADP+. During the light-dependent reactions of photosynthesis, electrons are transferred from photosystem I (PSI) to the primary electron acceptor, NADP+, which is reduced to NADPH. NADPH is then utilized in the Calvin cycle for the production of carbohydrates. it is a correct option.
