It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split
Explanation: During Light reactions of Photosynthesis, the chlorophyll located in the chloroplast will be activated by light energy from the sun. Thus the light activated chlorophyll will split the water molecule.
This process of splitting of water molecules is called Photolysis. Water molecule are splited to release Hydrogen ions and also oxygen.
there are two main types of explosive events in the Sun: solar flares and coronal mass ejections. Impulsive energy release in solar flares is one of the most dynamic and highly energetic phenomena in the Solar System
