**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the origin of coal. Specifically, it wants to know what remains coal is formed from.

2. **Identifying the Options**: The options provided are:
- A) Vegetation only
- B) Animal only
- C) Both vegetation and animals
- D) Neither vegetation nor animals

3. **Exploring Coal Formation**: Coal is formed through a process called carbonization. This process involves the transformation of organic material into coal over millions of years.

4. **The Role of Vegetation**: The primary source of coal is the remains of dead plants (vegetation). These plants get buried under soil and undergo changes due to high temperature and pressure over approximately 500 million years.

5. **Conclusion on Coal's Origin**: Since coal is derived from the remains of dead plants and not animals, we can conclude that coal is formed from vegetation only.
