Assertion : The cells that have membrane bound organelles are called eukaryotic.
Reason : The cells that lack membrane bound organelles are called prokaryotic.

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 solve the question regarding the assertion and reason about eukaryotic and prokaryotic cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Assertion**:
- The assertion states that "The cells that have membrane bound organelles are called eukaryotic."
- This is true because eukaryotic cells are characterized by the presence of membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, etc.

2. **Understand the Reason**:
- The reason states that "The cells that lack membrane bound organelles are called prokaryotic."
- This is also true as prokaryotic cells, such as bacteria, do not have membrane-bound organelles and instead have simpler structures.

3. **Evaluate the Relationship**:
- We need to determine if the reason is a correct explanation of the assertion.
- While both statements are true, the reason does not explain the assertion directly. The assertion defines eukaryotic cells, while the reason defines prokaryotic cells. They are related but do not provide a direct explanatory link.

4. **Conclusion**:
- Since both the assertion and reason are true, but the reason does not serve as a correct explanation for the assertion, the correct answer is: "Both assertion and reason are true but reason is not the correct explanation of assertion."

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