Explanation:

First Question (Multiple Choice)

Cars typically use gasoline as fuel. Burning gasoline can produce smog due to incomplete combustion and emissions of pollutants. Wood and coal are not common car fuels, and water cannot be burned as a fuel.

Fossil fuels (like coal, oil, natural gas) are formed from the remains of decaying organisms over millions of years. So the term here is "Fossil fuel".

Carbon dioxide is a greenhouse gas as it traps heat in the Earth's atmosphere, contributing to the greenhouse effect.

A. gasoline
