PLEASE HELP!!
The balanced equation for photosynthesis is shown below.

6 CO2 + 6 H2O → C6H12O6 + 6 O2
What best explains whether mass is conserved or not conserved during photosynthesis?

It is not conserved because the total number of H atoms is 6 more than the total number of C atoms.

It is not conserved because the total number of O atoms is 6 more than the total number of H atoms.

It is conserved because the total number of H atoms on each side is 12.

It is conserved because the total number of O atoms on each side is 2.
