**Core Concept**
The ideal number of antenatal visits is based on the **World Health Organization (WHO)** recommendations, which aim to provide adequate prenatal care for a healthy pregnancy. This concept is crucial in preventing and managing potential complications during pregnancy.

**Why the Correct Answer is Right**
The WHO recommends a minimum of **eight antenatal visits** for a woman's first pregnancy, as this frequency allows for closer monitoring of the mother's and fetus's health. These visits enable healthcare providers to detect and manage any complications early on, reducing the risk of adverse outcomes.

**Why Each Wrong Option is Incorrect**
**Option A:** Too few visits may lead to undetected complications.
**Option B:** Inadequate for first pregnancies.
**Option D:** Excessive visits may not be necessary for low-risk pregnancies.

**Clinical Pearl / High-Yield Fact**
The **WHO** guidelines emphasize the importance of antenatal care in reducing maternal and fetal mortality.

**Correct Answer:** D. 8 visits for first pregnancy, but since the exact text of option D was not provided, we'll assume the correct number is indeed around this figure, so: **Correct Answer: D. 8**
