Answer:

A. Decrease in CO2

Explanation:

This is due to the fact that in photosynthesis plants use carbon dioxide, water and sunlight to make sugar and oxygen. So Oxygen would have no impact on the rate photosynthesis occurs. And a increase in CO2 would increase its rate. Only when there is a lack of CO2 will the plant rate be impacted
