Correct option (d) Non-cyclic photophosphorylation
Explanation :
In photosynthesis during non-cyclic photophosphorylation involving both PS-I and PS-II, electrons released during photolysis of water are transfered to PS-II and then PS-i via a senes of electron carriers. P700 of PS-I releases electron after absorbing light energy. This electron passes through chlorophyll X, Fe-S, ferredoxin and finally to NADP+. NADP+ combines with H+(released during photolysis) with the help of NADP reductase to form NADPH.
