Which two action would most likely lead to an increase of carbon dioxide levels in the atmosphere?

The photo with the smoke emitting from the cars will increase the carbon dioxide in atmosphere by directly adding carbon dioxide (as well as other compounds such as sulfur and carbon monoxide). The photo that says "switch off" reduces consumption of electricity, which if done collectively, may reduce the burning of fossil fuels thereby reducing the carbon dioxide in atmosphere.

Ithink your answer will be c let me know if it’s right
