Which of the following is not a petroleum product?

Options

A. Gasoline
B. Cooking gas
C. Bees wax
D. All are petroleum producers

Answer

To determine which of the following options is not a petroleum product, we will analyze each option provided:

1. **Gasoline**: Gasoline, also known as petrol, is a refined product derived from crude oil. Therefore, it is a petroleum product.

2. **Cooking gas (LPG)**: Liquefied petroleum gas (LPG) is also derived from petroleum refining and natural gas processing. Thus, it is a petroleum product.

3. **Beeswax**: Beeswax is a natural wax produced by honeybees. It is not derived from petroleum or any petroleum refining processes. Hence, it is not a petroleum product.

4. **All of the above**: Since we have identified that both gasoline and cooking gas are petroleum products, this option cannot be correct.

Based on the analysis above, the correct answer is **Beeswax**, as it is not a petroleum product.

### Step-by-Step Solution:
1. Identify the first option: Gasoline - Confirm it as a petroleum product.
2. Identify the second option: Cooking gas (LPG) - Confirm it as a petroleum product.
3. Identify the third option: Beeswax - Confirm it is not a petroleum product.
4. Identify the fourth option: All of the above - Eliminate this option as it includes petroleum products.
5. Conclude that the answer is Beeswax.
