Assertion :- Cytoplasm is the main arena of cellular activities in both plants and animals.
Reason:- Various chemical reactions occur in it to keep the cell in the living state

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & 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 & Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Cytoplasm is the main arena of cellular activities in both plants and animals." This implies that the cytoplasm is where most of the metabolic processes occur in cells, regardless of whether they are plant or animal cells.

2. **Understanding the Reason**: The reason given is that "Various chemical reactions occur in it to keep the cell in the living state." This indicates that the cytoplasm is not just a passive medium but is actively involved in chemical reactions that are essential for maintaining life within the cell.

3. **Evaluating the Truth of the Assertion**: The assertion is true. Cytoplasm is indeed the site of many cellular activities, including metabolic pathways, synthesis of proteins, and other vital functions necessary for cell survival.

4. **Evaluating the Truth of the Reason**: The reason is also true. The cytoplasm contains various organelles and molecules that facilitate chemical reactions, such as glycolysis and protein synthesis, which are crucial for the cell's metabolic processes.

5. **Determining the Relationship Between Assertion and Reason**: The reason provides a correct explanation for the assertion. The fact that various chemical reactions occur in the cytoplasm supports the claim that it is the main arena of cellular activities.

6. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

**Final Answer**: Option 1 - Both assertion and reason are true, and reason is the correct explanation of assertion.
