Answer:
A. sugars
Step-by-step explanation:
The photosynthesis equation is:
CO2(carbon dioxide)+ H2O (water) +sunlight --> O2(oxygen) + C6H12O6 (glucose)
Photosynthesis makes sugar (glucose) and oxygen. But, oxygen is just oxygen, and there are no carbon atoms in O2.
Glucose is C6H12O6, and the C represents carbon. So, photosynthesis converts carbon atoms from CO2 to sugars.
Therefore, the choice is A.
