**Core Concept**
The ideal number of antenatal visits is a critical aspect of prenatal care, aiming to provide optimal monitoring and management of pregnancy-related complications. The World Health Organization (WHO) recommends a minimum of four antenatal visits, with specific guidelines for different stages of pregnancy.

**Why the Correct Answer is Right**
The ideal number of antenatal visits is based on the principle of providing regular check-ups to monitor fetal growth, maternal health, and detect potential complications early. The four visits are typically scheduled at:
* First visit: 12-16 weeks of gestation for initial assessment and risk factor identification.
* Second visit: 24-28 weeks for detailed fetal anatomy scan and blood pressure monitoring.
* Third visit: 32-36 weeks for assessment of fetal growth and onset of labor.
* Fourth visit: 38-40 weeks for induction of labor or preparation for cesarean delivery.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as it does not follow the recommended guidelines by the World Health Organization.
* **Option B:** This option is incorrect as it may not provide adequate monitoring and management of pregnancy-related complications.
* **Option C:** This option is incorrect as it may lead to inadequate assessment and detection of potential complications.

**Clinical Pearl / High-Yield Fact**
Regular antenatal visits are crucial in reducing maternal and fetal morbidity and mortality. Early detection and management of complications can improve pregnancy outcomes.

**Correct Answer:** A. Four visits.
