Assertion: Calophyllum leaf has parallel venation.
Reason: It is the plant of dicot group of angiosperms.

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 the Reason is not the correct explanation of the Assertion.
C. If Assertion is true, but Reason is false.
D. If both Assertion and Reason are false.

Answer

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

### Step 1: Understand the Assertion
The assertion states that "Calophyllum leaf has parallel venation."
- **Definition of Venation**: Venation refers to the arrangement of veins in the leaf. In parallel venation, the veins run parallel to each other without forming a network.

### Step 2: Understand the Reason
The reason given is that "It is the plant of dicot group of angiosperms."
- **Dicots vs. Monocots**: Typically, dicot plants exhibit reticulate venation, where the veins form a network, while monocots usually show parallel venation.

### Step 3: Analyze the Relationship
- **Calophyllum Classification**: Calophyllum is classified as a dicot, yet it exhibits parallel venation, which is unusual since parallel venation is predominantly found in monocots.

### Step 4: Evaluate the Statements
- **Assertion**: True, Calophyllum does have parallel venation.
- **Reason**: True, Calophyllum is a dicot, but the reason does not explain why it has parallel venation.

### Conclusion
Both the assertion and the reason are true, but the reason does not correctly explain the assertion. Therefore, the correct answer is that both statements are true, but the reason is not a correct explanation of the assertion.

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