Assertion: Disruption of the natural structural of a protein is called denaturation.
Reason: The change in colour and apperance of egg during cooking is due to denaturation.

Options

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

Explanation

To analyze the given question, we need to evaluate both the assertion and the reason provided.

### Step 1: Understanding the Assertion
The assertion states that "Disruption of the natural structure of a protein is called denaturation."
- **Explanation**: Denaturation refers to the process where proteins lose their native structure due to external factors such as heat, pH changes, or chemical agents. This disruption alters the protein's biological activity and function.

### Step 2: Understanding the Reason
The reason states that "The change in color and appearance of egg during cooking is due to denaturation."
- **Explanation**: When an egg is cooked, the proteins within it undergo denaturation. The liquid egg white (albumin) transforms into a solid white and changes color due to the denaturation of proteins, which lose their original structure and form new bonds.

### Step 3: Evaluating the Relationship
Now we need to evaluate the relationship between the assertion and the reason.
- The assertion is true because denaturation indeed refers to the disruption of a protein's natural structure.
- The reason is also true because the cooking of an egg does lead to changes in color and appearance due to protein denaturation.

### Step 4: Conclusion
However, while both statements are true, the reason does not provide a direct explanation for the assertion. The assertion is a general statement about denaturation, while the reason is a specific example of denaturation occurring in eggs. Therefore, the correct conclusion is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
