The path of an electron during the light reactions of photosynthesis it is best

Question

The path of an electron during the light reactions of photosynthesis it is best described this way:
PS I ETC I PS II ETC II water NADPH water PSII ETC II PS I ETC I NADPH ETC I PS I NADPH ETC II PS I water PS II ETC II PS I ETC I NADPH water
The path of an electron during the light reactions of photosynthesis it is best described this way:
PS I ETC I PS II ETC II water NADPH water PSII ETC II PS I ETC I NADPH ETC I PS I NADPH ETC II PS I water PS II ETC II PS I ETC I NADPH water
The path of an electron during the light reactions of photosynthesis it is best described this way:
PS I ETC I PS II ETC II water NADPH water PSII ETC II PS I ETC I NADPH ETC I PS I NADPH ETC II PS I water PS II ETC II PS I ETC I NADPH water

Explanation / Answer

Answer is option b.

The path of electron flow during photosynthesis,first the source of electron is water then it is moved through PSII and then PS l after that it goes ETC I and atlast the electron acceptor is NADPH.

So,option a,c and d are not correct.

The above mentioned sequence matches with option b.

Hence,option b is correct.
