D. If both Assertion & Reason are false.

Answer

To solve the question regarding the assertion and reason about reptiles, we will follow these steps:

### Step 1: Analyze the Assertion
The assertion states that "The body of reptiles is covered by dry and cornified skin, epidermal scales or scutes."
- This statement is **true**. Reptiles have a specialized skin that is dry and made up of scales or scutes, which helps them retain moisture in their terrestrial environment.

### Step 2: Analyze the Reason
The reason states that "Reptiles are true terrestrial vertebrates."
- This statement is also **true**. Reptiles are indeed classified as true terrestrial vertebrates because they have adapted to live on land and possess features that support this lifestyle.

### Step 3: Evaluate the Relationship Between Assertion and Reason
Now we need to determine if the reason provided is a correct explanation of the assertion.
- The assertion explains the physical characteristics of reptiles, while the reason explains their classification as terrestrial vertebrates. Although both statements are true, the reason does not directly explain why reptiles have dry and cornified skin or scales.

### Conclusion
Since both the assertion and reason are true, but the reason does not explain the assertion, the correct answer is:
- **Option 2**: Both assertion and reason are true, but reason is not the correct explanation of assertion.
