Answer

**Step-by-Step Solution:**

1. **Understanding Petroleum**: Petroleum is a natural resource that is primarily composed of hydrocarbons. It is often referred to as crude oil in its raw form.

2. **Identifying the Options**: The question asks for the main source of petroleum among the given options, which include Silk, Plastic, Cotton, and Jute.

3. **Evaluating Silk**: Silk is a natural fiber produced by silkworms. It is not derived from petroleum. Therefore, petroleum is not the main source of silk.

4. **Evaluating Plastic**: Plastic is a synthetic material that is derived from petroleum. During the refining process of crude oil, various fractions are obtained, one of which is naphtha, a crucial compound for the production of plastics. Thus, petroleum is indeed the main source of plastic.

5. **Evaluating Cotton**: Cotton is a natural fiber obtained from the cotton plant. It is not derived from petroleum, so petroleum is not the main source of cotton.

6. **Evaluating Jute**: Jute is another natural fiber obtained from the jute plant. Similar to cotton, it is not derived from petroleum, making it incorrect to say that petroleum is the main source of jute.

7. **Conclusion**: Based on the evaluations, the only option where petroleum serves as the main source is Plastic. Therefore, the correct answer is that petroleum is the main source of plastic.

**Final Answer**: Petroleum is the main source of Plastic.
