During electron transport system1)reduction of NADP into NADPH + H+ Occurs2) oxidation of NADP occurs3) phosphorylation of NADP occurs4)Hydrogenation of FAD occurs

In the electron transport chain in photosynthesis-the electrons react with a carrier molecule nicotinamide adenine dinucleotide phosphate (NADP), changing it from its oxidised state (NADP+) to its reduced state (NADPH):

NADP++ 2e-+ 2H+ [-->] NADPH + H+
so option A is correct
