Assertion :- The process of splicing represents the dominance of RNA world.
Reason:- In the process of splicing exons are removed and introns are joined in a defined order.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Answer

To analyze the given assertion and reason, we will break down the statements and evaluate their validity.

### Step 1: Understand the Assertion
The assertion states that "The process of splicing represents the dominance of RNA world."
- **Evaluation**: This statement is true. The RNA world hypothesis suggests that early life forms may have relied primarily on RNA for both genetic information and catalysis. Splicing, which involves the processing of RNA, supports the idea that RNA played a central role in early biological processes.

### Step 2: Understand the Reason
The reason states that "In the process of splicing, exons are removed and introns are joined in a defined order."
- **Evaluation**: This statement is false. In the splicing process, introns (non-coding regions) are removed, and exons (coding regions) are joined together. Therefore, the description in the reason is incorrect as it mistakenly states that exons are removed and introns are joined.

### Step 3: Conclusion
- The assertion is true, but the reason is false. The reason does not correctly explain the assertion. Therefore, while both statements are related to the process of RNA splicing, only the assertion holds true in the context of the RNA world hypothesis.

### Final Answer
- **Assertion**: True
- **Reason**: False
