**Core Concept**
Low birth weight (LBW) is a critical indicator of maternal and neonatal health. It is defined as a birth weight of less than 2,500 grams (5.5 pounds), which can be associated with increased risks of neonatal mortality, morbidity, and long-term health consequences.

**Why the Correct Answer is Right**
The correct answer is the most effective and commonly used method to display low birth weight statistics. This method provides a clear visual representation of the distribution of birth weights, allowing healthcare professionals to easily identify trends, patterns, and outliers. By using a histogram or a bar chart, healthcare providers can quickly assess the prevalence of low birth weight and make informed decisions to improve maternal and neonatal care.

**Why Each Wrong Option is Incorrect**
**Option A:** Scatter plot - While scatter plots can be used to display relationships between variables, they are not the best choice for displaying low birth weight statistics, as they can be cluttered and difficult to interpret.

**Option B:** Pie chart - Pie charts are not suitable for displaying low birth weight statistics, as they can be misleading and do not provide a clear representation of the distribution of birth weights.

**Option C:** Line graph - Line graphs can be used to display trends over time, but they are not the best choice for displaying low birth weight statistics, as they can be difficult to read and do not provide a clear representation of the distribution of birth weights.

**Clinical Pearl / High-Yield Fact**
When displaying low birth weight statistics, it is essential to use a clear and concise title, label the axes correctly, and provide a key or legend to explain the data.

**Correct Answer: C. Bar chart. Bar chart is the most effective and commonly used method to display low birth weight statistics.**
