detailed solution

Correct option is B

During non-cyclic photophosphorylation, electrons are excited from PS II and PS I simultaneously on absorbing photons of suitable wavelengths. Electron deficiency in PS II is fulfilled by electrons generated by photolysis of water and electron deficiency of PS I is fulfilled by electrons coming from PS II. The electrons that were excited from PS I finally end up with the formation of NADPH+H+ molecules.
