Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.

Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.

Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.

So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution
