Photosystem I contains reaction center:

AP680
BP700 (absorbs at 700 nm)
CP420
DP800
Answer & Solution
Correct answer: B. P700 (absorbs at 700 nm)
PS I: reaction center P700. After excitation, P700* passes electron to ferredoxin → NADP+ reductase → produces NADPH. Light hit PS I → P700+ becomes strong oxidant; gets re-reduced by PC (electrons from PSII). Z-scheme: PSII pushes electrons up to PSI, then to NADP+.
