Electrons excited by absorption of light in PSI are transferred to the primary acceptors, and therefore must be replaced. The replacements come directly from (1) NADP (2) ATP (3) P811 (4) Water..

Dear student
Please refer the solution below for the said query
Your question is not clear.
The option 3rd should be PSII. Then only the answer will be option 3.
The electrons excised from PSI are directly replaced from PSII (Photosystem II).
Hope this information clears your doubt about the topic.

The electrons excised from PSI are directly replaced from PSII (Photosystem II).
PS II absorbs 680 nm wavelength of red light, causing electrons to become excited and jump into an orbit farther from the nucleus.These electrons are then accepted by an electron acceptor, which sends them to an electron transport system. Electron transport system transfers the electrons to PS I.
Hope this information clears your doubt about the topic.
