Which statement best evaluates the claim, "The oxygen-evolving complex replaces the high-energy electron that leaves chlorophyll with another high-energy electron from water"?
A
The claim is fully correct because water electrons are high-energy before light absorption.
B
The claim is wrong because oxygen gas provides high-energy electrons to chlorophyll.
C
The claim is wrong because carbon dioxide, not water, replaces electrons in photosystem II.
D
The source is correct, but the replacement electron from water is not described as high-energy until light-driven transfers raise electron energy in photosystems.
