## Core Concept
The human skeleton is composed of bones that fuse together during growth and development. At birth, the skeleton is made up of more bones than in adulthood because many of these bones fuse together as a person grows.

## Why the Correct Answer is Right
A neonate, or newborn, has approximately 300 bones in their skeleton. This number is higher than in adults because many of the bones in the neonatal skeleton are not yet fused together. For example, the bones of the skull are not fused at birth, allowing for the bones to overlap and make the passage through the birth canal easier. As a person grows and develops, many of these bones fuse together, reducing the total number of bones in the adult skeleton to approximately 206.

## Why Each Wrong Option is Incorrect
* **Option A:** This option is incorrect because it does not accurately reflect the number of bones in a neonate's skeleton.
* **Option B:** This option is incorrect because it likely represents a number that is too low for a neonate but could be closer to the correct number of bones in an adult skeleton.
* **Option D:** This option is incorrect because it suggests a number that is significantly higher or lower than the actual number of bones in a neonate's skeleton.

## Clinical Pearl / High-Yield Fact
It's essential to remember that the neonatal skeleton has more bones than the adult skeleton due to the presence of cartilaginous areas that have not yet ossified or fused. A classic example is the skull, which has multiple bones that fuse together as the child grows. This fact can be crucial in pediatric radiology and understanding developmental anatomy.

**Correct Answer: C. 300.**
