Answer:

A) splitting water molecules I believe

When oxygen is released as a result of photosynthesis, it is a direct by-product of splitting water molecules.

PHOTOSYNTHESIS:

  • Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight.

  • Photosynthesis occurs in two stages namely: light dependent reaction and light independent reaction.

  • In the light dependent reaction, chlorophyll molecules absorb light and the released electron is used to split water molecules into hydrogen and oxygen gas.

  • Therefore, the release of oxygen gas is a direct byproduct of the splitting of water molecules called photolysis.
