Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
In the light of the above statements choose the correct answer from the options given below:
| Assertion (A): | Cyclic photophosphorylation results in the synthesis of ATP but not of NADPH + H+. |
| Reason (R): | The excited electron does not pass on to NADP+ but is cycled back to the PS I complex through the electron transport chain. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
