Answer:
A
Solution:
In far-red light (wavelength more than 680 nm), there is a reduction in the quantity of O2evolution.
The evolution of oxygen as a result of light-driven water
oxidation in photosystem II (PSII) is catalyzed by anMn2+ cluster that acts both as a device for accumulating oxidizing equivalents and as the active site.
Infrared ray disturbs this complex and hence reduction on O2 evolution.
