Answer:
The correct answer is C. NADP⁺
Explanation:
NADP+ is the coenzyme that acts as the electron carrier during the photosynthetic process. The electron that is released from the splitting of water pass through the electron transport chain and at the end of the chain the electron is received by an electron carrier called NADP+.
So this passing of electron causes the transport of H ions in the thylakoid lumen from the stroma and when these ions come back through ATP synthase it forms ATP. Then these NADPH and ATP are used in the Calvin cycle to fix the CO2 into complex form. Therefore the correct answer is C. NADP⁺.
