Question

which is a fossil fuel?
a. nuclear
b. coal

Explanation:

Fossil fuels are formed from the remains of ancient plants and animals over millions of years. Coal is formed from plant matter that has been subjected to heat and pressure over time, making it a fossil fuel. Nuclear energy comes from nuclear reactions, biomass is organic matter from living or recently living organisms, and geothermal energy is from Earth's internal heat, so they are not fossil fuels.
