Read the statements and choose the correct option.
Statement I: In non-cyclic photophosphorylation, electrons are not returned to the photosystem from which they started.
Statement II: In cyclic photophosphorylation, ATP and NADPH are both formed.

(a) Both Statement I and Statement II are true. Your answer
(b) Both Statement I and Statement II are false. Your answer
(c) Statement I is true but Statement II is false. Correct
(d) Statement I is false but Statement II is true. Your answer

Your answer: Correct answer: (c)

Explanation

Why (c) is correct

Statement I is true: in non-cyclic flow, electrons from water end up in NADPH and do not return to their photosystem. Statement II is false: cyclic flow makes ATP only.

Why the other options are wrong

(a) · your answer Statement II is false.
(b) · your answer Statement I is true.
(d) · your answer Statement I is true and II false.

NCERT point: Non-cyclic: water → NADP⁺. Cyclic: PS I → PS I.
