Which of these is a FOSSIL FUEL? Natural gas Nuclear Fuel Wind Power Wood

## Step 1:To determine which among the given options is a fossil fuel, we need to identify the characteristics of a fossil fuel. Fossil fuels are formed from decomposition of remains of plants and animals over millions of years and are rich in hydrocarbons.## Step 2:Let's examine each option individually.### : This is a type of fossil fuel, as it is formed from the remains of ancient organic matter and contains hydrocarbons.### : This is not a fossil fuel. It's a renewable form of energy derived from wind flow.### : This is not a fossil fuel. It refers to the use of a nuclear reactor to generate heat, which is used in power plants to generate electricity.### : Although it comes from plants, wood is not a fossil fuel. It is a renewable resource and does not contain hydrocarbons in the same way fossil fuels do.
