Explosion is the evolution of:

Options

A. heat
B. light
C. sound
D. all of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Explosion**:
- An explosion is defined as a rapid increase in volume and the release of energy in a dramatic manner. This means that during an explosion, a substance undergoes a significant change in size and releases energy quickly.

2. **Identifying the Forms of Energy Released**:
- When an explosion occurs, energy is released in various forms. We need to identify these forms to answer the question correctly.

3. **Heat**:
- During an explosion, heat is generated. This can be observed in many explosive reactions where the temperature increases significantly.

4. **Light**:
- Explosions often produce a bright flash of light. This is due to the rapid release of energy that excites particles, causing them to emit light.

5. **Sound**:
- Explosions are typically accompanied by a loud sound. This sound is a result of the rapid expansion of gases and the shock waves produced during the explosion.

6. **Conclusion**:
- Since explosions result in the release of heat, light, and sound, we can conclude that the evolution of an explosion includes all these forms of energy.

7. **Final Answer**:
- Therefore, the correct answer to the question "Explosion is the evolution of:" is **all of these** (heat, light, and sound).
