Answer:
The correct answer is b water is split through photon energy into hydrogen ions,electron and oxygen.
Explanation:
During light reaction of photosynthesis light energy is absorbed by the antenna complex of photosystem 1and photosystem 2.
        The absorbed light is used to split water in proton (H+) and hydroxyl ion(OH-). The hydroxyl ion losses its electron to from hydroxyl radical(OH)
        The hydroxyl radical then undergo breakdown to form oxygen and water molecules.
 H2O=H+  +  OH-
 OH-  -e = OH
  4OH=2H2O+O2
