$ Kingdom Monera includes the unicellular prokaryotic organisms.
! Eukaryotes are the organisms which have a eukaryotic nucleus and double membraned organelles.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Kingdom Monera includes unicellular prokaryotic organisms." We need to analyze if this statement is true.
- **Explanation**: Kingdom Monera is indeed composed of unicellular organisms, primarily bacteria, which are classified as prokaryotes. Prokaryotic cells lack a well-defined nucleus and membrane-bound organelles.

2. **Understanding the Reason**: The reason given is "Eukaryotes are organisms which have a eukaryotic nucleus and double membraned organelles." We must determine if this statement is true and if it relates to the assertion.
- **Explanation**: This statement is also true. Eukaryotic cells have a true nucleus, which is membrane-bound, and they contain various membrane-bound organelles such as mitochondria, Golgi apparatus, and endoplasmic reticulum.

3. **Evaluating the Relationship**: Now we need to assess whether the reason provided correctly explains the assertion.
- **Explanation**: While both statements are true, the reason does not explain the assertion. The assertion is about prokaryotic organisms in Monera, whereas the reason discusses eukaryotic organisms, which are a different classification altogether.

4. **Conclusion**: Based on the analysis, we conclude that:
- The assertion is true.
- The reason is true, but it does not explain the assertion. Therefore, the correct answer is that the assertion is correct, and the reason is also correct, but the reason is not the correct explanation of the assertion.

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