## **Core Concept**
The classification of newborns based on their birth weight is crucial for assessing their health risks and guiding medical care. Newborns are categorized into different weight groups to identify those at higher risk for complications. The terms used to describe these weight categories are essential for medical professionals to understand.

## **Why the Correct Answer is Right**
The correct term for a newborn whose weight is less than 1500 g is **Very Low Birth Weight (VLBW)**. This classification is significant because babies with VLBW are at a higher risk for health complications, such as respiratory distress syndrome, infections, and long-term developmental issues. The classification helps in providing appropriate care and interventions.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but typically, incorrect options might include terms like "Low Birth Weight" (which usually refers to babies weighing less than 2500 g), "Normal Birth Weight," or "Extremely Low Birth Weight" (which refers to babies weighing less than 1000 g).
- **Option B:** Without the specific term, it's hard to address directly, but any term not specifically referring to a weight less than 1500 g would be incorrect in this context.
- **Option C:** Similarly, without the term, we can infer that if it does not accurately describe a newborn weighing less than 1500 g, it would be incorrect.
- **Option D:** This option is also not provided, but it would be incorrect if it does not match the definition of Very Low Birth Weight.

## **Clinical Pearl / High-Yield Fact**
A crucial point to remember is that **Very Low Birth Weight (VLBW) infants** are those with a birth weight of less than 1500 g, and **Extremely Low Birth Weight (ELBW)** infants are those with a birth weight of less than 1000 g. These classifications are vital for the management and prognosis of newborns.

## **Correct Answer:** C. Very Low Birth Weight.
