C Correct answer
Explanation

RuBP (Ribulose-1,5-bisphosphate) is the first compound to accept CO2 in the Calvin cycle (dark phase of photosynthesis). This reaction is catalyzed by RuBisCO enzyme. NADP and Ferredoxin are involved in electron transport, while Cytochrome is part of electron transport chain.
