Solution

The correct option is B
a & c are correct

Cyclic Photophosphorylation is the process, in which systems (like prokaryotes). This type of photophosphorylation usually occurs in the thylakoid membrane. The electron begins in a pigment complex called photosystem I in cyclic electron flow. It produces neither oxygen nor NADPH.
