Assertion : Kerosene is a fossil fuel.
Reason : Kerosene is not obtained as a fraction of fractional distillation of petroleum.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To analyze the assertion and reason provided in the question, we can break it down into steps:

### Step 1: Understanding the Assertion
- **Assertion**: Kerosene is a fossil fuel.
- 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. Kerosene is derived from petroleum, which is itself a fossil fuel.

### Step 2: Understanding the Reason
- **Reason**: Kerosene is not obtained as a fraction of fractional distillation of petroleum.
- This statement is incorrect. Kerosene is actually one of the fractions obtained from the fractional distillation of crude oil (petroleum). During this process, different components of petroleum are separated based on their boiling points, and kerosene is one of those components.

### Step 3: Conclusion
- Since the assertion is true (kerosene is indeed a fossil fuel) but the reason is false (kerosene is obtained from fractional distillation of petroleum), we can conclude that the correct answer is that the assertion is true, but the reason is false.

### Final Answer
- The assertion is true, and the reason is false.
