B. Hanskrebs
C. Robert Brown
D. Joseph Priestely

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks who demonstrated that certain plants can serve as a source of hydrocarbons.

2. **Identifying Hydrocarbon Plants**: Hydrocarbon plants are those that produce hydrocarbons, which are organic compounds made entirely of hydrogen and carbon. These plants can produce substances similar to petroleum, known as terpenoids.

3. **Exploring the Options**:
- **Melvin Kelvin**: He is known for his work related to hydrocarbon plants and specifically studied the Euphorbia family, which includes the rubber tree (Hevea). He showed that these plants can produce hydrocarbons.
- **Hans Krebs**: He is known for discovering the urea cycle, which is unrelated to hydrocarbons.
- **Robert Brown**: He discovered Brownian motion, which pertains to the random movement of particles, not hydrocarbons.
- **Joseph Priestley**: He is famous for discovering oxygen, with no connection to hydrocarbon plants.

4. **Conclusion**: Based on the analysis of the options, Melvin Kelvin is the correct answer as he demonstrated that certain plants can function as a source of hydrocarbons.

**Final Answer**: Melvin Kelvin
