Name the fossil fuel used in making food, railway engine and thermal power plants :

Options

A. Coal
B. Petroleum
C. Natural gas
D. None of these

Explanation

To solve the question, "Name the fossil fuel used in making food, railway engine, and thermal power plants," we can follow these steps:

### Step 1: Identify the fossil fuels
The three main fossil fuels we will consider are:
1. Natural gas
2. Petroleum
3. Coal

### Step 2: Analyze the uses of each fossil fuel
- **Natural Gas**:
- Commonly used for cooking (making food).
- Used in some thermal power plants.
- Not typically used in railway engines.

- **Petroleum**:
- Primarily used for transportation fuels (like gasoline and diesel).
- Not used in making food directly.
- Can be used in some power generation but not in thermal power plants in the same way coal is.

- **Coal**:
- Used in thermal power plants for electricity generation.
- Historically used in railway engines as a fuel source.
- Can be used indirectly in food preparation (for example, in traditional cooking methods).

### Step 3: Match the fossil fuel with the uses mentioned in the question
- The question specifies three uses: making food, railway engines, and thermal power plants.
- **Natural gas** does not fit all three.
- **Petroleum** does not fit the food-making aspect.
- **Coal** fits all three categories:
- It can be used in cooking (especially in traditional methods).
- It is used in railway engines.
- It is widely used in thermal power plants.

### Conclusion
The fossil fuel used in making food, railway engines, and thermal power plants is **Coal**.
