Assertion: Stroma lamellae have both PS I and PS II but the membrane of grana lack PS II as well as NADP reductase.
Reason: Cyclic photophosphorylation also occurs when only light of wavelength below 680 nm is available for excitation.

A

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.
