Options

A. coal and wood
B. coal and petroleum
C. coal tar and charcoal
D. LPG and coke

Explanation

To solve the question regarding what fossil fuel is a mixture of, we will analyze each option provided and determine which one correctly identifies fossil fuels.

### Step-by-Step Solution:

1. **Understanding Fossil Fuels**:
- Fossil fuels are natural substances formed from the remains of ancient plants and animals that have been subjected to heat and pressure over millions of years. They primarily consist of hydrocarbons.

2. **Analyzing the Options**:
- **Option A: Coal and Wood**:
- Coal is a fossil fuel, but wood is not. Wood is a biomass fuel and does not undergo the same geological processes as fossil fuels.
- **Option B: Coal and Petroleum**:
- Both coal and petroleum are fossil fuels. Coal is formed from plant matter, while petroleum is derived from the remains of marine organisms. This option correctly identifies a mixture of fossil fuels.
- **Option C: Coal Tar and Charcoal**:
- Coal tar is a byproduct of coal processing, and charcoal is produced from burning wood in a low-oxygen environment. Neither of these is a fossil fuel in the traditional sense.
- **Option D: LPG and Coke**:
- LPG (Liquefied Petroleum Gas) is derived from natural gas and petroleum, while coke is a fuel derived from coal. This option does not represent a mixture of fossil fuels.

3. **Conclusion**:
- After analyzing all the options, the correct answer is **Option B: Coal and Petroleum**. Both are recognized fossil fuels.

### Final Answer:
Fossil fuel is the mixture of **Coal and Petroleum**.
