In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it of the statements mark the correct answer as
Assertion(A):The number of cells in a multicellular organism is inversely proportional to size of body
Reason:all cells of biological world are alive

Options

A. Both Assertion and Reason is the correct explanation of Assertion
B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
C. Assertion is true but Reason is false
D. Both Assertion and Reason are false

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states: "The number of cells in a multicellular organism is inversely proportional to the size of the body."
- This means that as the size of the organism increases, the number of cells decreases. This is not accurate because larger organisms generally have more cells, not fewer. Therefore, the assertion is **false**.

2. **Understanding the Reason**:
- The reason states: "All cells of the biological world are alive."
- This statement is also inaccurate because there are many types of cells, including dead cells (like cork cells and the outer layer of skin cells). Thus, the reason is **false**.

3. **Conclusion**:
- Since both the assertion and the reason are false, we can conclude that the correct answer is option D: Both Assertion and Reason are false.

### Final Answer:
Both Assertion and Reason are false.
