Assertion: Vagina acts as copulation canal and fertilization canal.
Reason: Both insemination and fusion of gametes occur in vagina of female.

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 provided, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states that "Vagina acts as copulation canal and fertilization canal."
- **Copulation Canal**: This part is true. The vagina is indeed the canal through which copulation (the act of mating) occurs.
- **Fertilization Canal**: This part is false. Fertilization does not occur in the vagina; it occurs in the fallopian tubes.

### Step 2: Analyze the Reason
The reason states that "Both insemination and fusion of gametes occur in the vagina of female."
- **Insemination**: This is true. Insemination (the introduction of sperm into the female reproductive tract) occurs in the vagina.
- **Fusion of Gametes**: This is false. The fusion of gametes (fertilization) occurs in the fallopian tubes, not in the vagina.

### Step 3: Conclusion
Now, we can conclude:
- The assertion is partially true (true for copulation, false for fertilization).
- The reason is false because it incorrectly states where fertilization occurs.

### Final Answer
Since the assertion is partially true and the reason is false, the correct answer is:
**Assertion is true and reason is false.**
