Assertion: Members of protists are eukaryotes.
Reason: Protistan cell body does not contain a well defined nucleus and other membrane bounded cell organelles.

Options

A. If both assertion and Reason are true and the reason is a correct explanation of the assertion.
B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion and Reason are False.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Members of protists are eukaryotes." This is true because protists are indeed classified as eukaryotic organisms. Eukaryotes are characterized by having cells with a well-defined nucleus and membrane-bound organelles.

2. **Understanding the Reason**: The reason provided states, "Protistan cell body does not contain a well-defined nucleus and other membrane-bounded cell organelles." This statement is false. Protists, being eukaryotes, do contain a well-defined nucleus and membrane-bound organelles.

3. **Analyzing the Relationship**: Since the assertion is true and the reason is false, we need to evaluate the relationship between them. The reason does not correctly explain the assertion because it contradicts the definition of protists as eukaryotes.

4. **Conclusion**: Based on the analysis, the correct answer is that the assertion is true, but the reason is false.

**Final Answer**: Assertion is true, but reason is false.
