Assertion: Euglenoids can preform photosynthesis.
Reason: They have chloroplast in cytoplasm..
Reason: They have chloroplast in cytoplasm.

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 "Euglenoids can perform photosynthesis." This is true because Euglena, a type of euglenoid, contains chlorophyll, which allows it to capture light energy and convert it into chemical energy through photosynthesis.

2. **Understanding the Reason**: The reason provided is "They have chloroplast in cytoplasm." This is also true. Euglenoids possess chloroplasts that contain chlorophyll, enabling them to perform photosynthesis.

3. **Analyzing the Relationship**: Now, we need to determine if the reason is a correct explanation of the assertion. Since the presence of chloroplasts in the cytoplasm is what enables Euglena to perform photosynthesis, the reason directly supports the assertion.

4. **Conclusion**: Both the assertion and the reason are true, and the reason is indeed a correct explanation of the assertion. Therefore, the correct answer is: "Both assertion and reason are true, and the reason is the correct explanation of the assertion."

**Final Answer**: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
