Assertion (A): \( \mathrm{H}^{+} \)concentration in stroma decreases in light phase.
\( \mathrm{P} \)
Reason (R): Formation of NADPH withdraws H+ from lumen.
(1) Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
(2) Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A).
(3) Assertion (A) is true and Reason (R) is false.
(4) Assertion (A) and Reason (R) both are false.
