### Analysis of Options
1. **Combustion**: This is a chemical reaction that releases energy, primarily seen in fires and engines. It does not involve nuclear reactions.
2. **Fission**: This is the process of splitting heavy atomic nuclei (like Uranium-235 or Plutonium-239) to release a significant amount of energy. Fission is indeed the principle used in atomic bombs.
3. **Fusion**: This is the process of combining light atomic nuclei (like Hydrogen isotopes) to form heavier nuclei, releasing energy. Fusion is the principle behind hydrogen bombs.
4. **Gravity**: This is a fundamental force of attraction between masses but does not produce energy in the context of nuclear weapons.

### Conclusion
The options related to fission and fusion both represent processes used in different types of nuclear weapons. Atomic bombs rely on **fission**, while hydrogen bombs utilize **fusion**.

### Final Answer
The source of energy in nuclear weapons is primarily **B. Fission** (for atomic bombs) and **C. Fusion** (for hydrogen bombs).
