Which of the following is the primary electron acceptor from the chlorophyll molecule of Photosystem-$II$?

In photosystem $II$, the reaction centre chlorophyll-a absorbs $A$ nm wavelength of red light, causing electrons to become excited and jump into an orbit farther from the atomic nucleus. These electrons are picked up by an $B$, which passes them to an electron transport system consisting of $C$. Pick the right choice for $A, B$ and $C$.

The reaction center that accepts light energy in Photosystem-$II$ is .........
