In each of the following questions, a statement of Assertion is given followed by corresponding statement of Reason of the statement, mark the correct alternative as directed below.
Assertion : In mitosis, two identical cells are produced from a single cell, and karyokinesis is followed by cytokinesis.
Reason: Cytokinesis is of two types.

Options

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

Answer

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

### Step 1: Analyze the Assertion
**Assertion:** In mitosis, two identical cells are produced from a single cell, and karyokinesis is followed by cytokinesis.

- **Explanation:** Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. This process involves karyokinesis, which is the division of the nucleus, followed by cytokinesis, which is the division of the cytoplasm. Therefore, the assertion is true.

### Step 2: Analyze the Reason
**Reason:** Cytokinesis is of two types.

- **Explanation:** Cytokinesis can indeed occur in two different ways depending on the type of cell. In animal cells, cytokinesis occurs through a process called cleavage furrow formation, while in plant cells, it occurs through the formation of a cell plate. Thus, the reason is also true.

### Step 3: Determine the Relationship Between Assertion and Reason
- While both the assertion and the reason are true, the reason does not provide a proper explanation for the assertion. The assertion focuses on the outcome of mitosis (the production of identical cells), while the reason discusses the types of cytokinesis without directly explaining why the assertion is true.

### Conclusion
Based on the analysis:
- **Assertion:** True
- **Reason:** True
- **Relationship:** The reason is not a correct explanation of the assertion.

### Final Answer
The correct alternative is: **Assertion and reason are true. Reason is not correct explanation of assertion.**
