Assertion : Cycle photophosphorylation synthesizes ATP.
Reason : ATP synthesize in cyclic photophosphorylation is not assoiated with NADPH formation.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
