Which of the following is an advantage nuclear fission has over fossil fuels?

Options

A. unlimited supply of fuel
B. less radioactive waste
C. fewer building expenses
D. less released carbon dioxide

Explanation

**Step-by-Step Solution:**

1. **Understanding Nuclear Fission:**
- Nuclear fission is a process where the nucleus of an atom, such as uranium, splits into smaller parts (nuclei) when it collides with a neutron. This process releases a significant amount of energy.

2. **Understanding Fossil Fuels:**
- Fossil fuels, such as coal, oil, and natural gas, are derived from ancient organic matter. When burned, they release energy but also produce carbon dioxide (CO2) and other pollutants.

3. **Comparing Energy Sources:**
- One of the main advantages of nuclear fission over fossil fuels is the amount of energy produced per unit of fuel. Nuclear fission generates a much larger amount of energy compared to the energy released from burning fossil fuels.

4. **Environmental Impact:**
- A significant advantage of nuclear fission is that it produces less carbon dioxide compared to fossil fuels. The burning of fossil fuels releases a considerable amount of CO2, contributing to climate change.

5. **Conclusion:**
- Therefore, the advantage of nuclear fission over fossil fuels is that it releases less carbon dioxide during energy production.

**Final Answer:**
Nuclear fission has the advantage of releasing less carbon dioxide compared to fossil fuels.
