Correct option (b) Photosystem-II

Explanation :

NADPH is generated through photosystem-II. In non-cyclic photophosphorylation (which involves both PS-I and II) protons released from photolysis and electrons emitted from P700 are ultimately passed on to NADP+ resulting in the formation of NADPH. 

In cyclic photophosphorylation (which involvesa only PS-I) electrons flow in a cyclic manner but there is no net formation of NADPH and O2
