The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "Cervix contains the largest and the most powerful sphincter muscle in the body." To analyze this, we need to recognize the role of the cervix in the female reproductive system. The cervix is indeed a muscular structure that plays a crucial role in maintaining pregnancy by holding the fetus and the amniotic fluid. 2. **Understanding the Reason**: The reason provided is "Cervix opens into the vagina by external OS." This statement is also true. The cervix has two openings: the internal os (which connects to the uterus) and the external os (which opens into the vagina). 3. **Evaluating the Relationship**: Now we need to evaluate if the reason provided is the correct explanation for the assertion. While both statements are true, the reason does not explain why the cervix contains the largest and most powerful sphincter muscle. The strength of the cervical muscles is related to their function in supporting the weight of the fetus and maintaining pregnancy, rather than merely the fact that it opens into the vagina. 4. **Conclusion**: Since both the assertion and the reason are true, but the reason does not correctly explain the assertion, the correct answer is option B: "Both assertion and reason are true but reason is not the correct explanation of the assertion."
