**Core Concept**
The spinal cord in infants is anatomically distinct from that in adults due to the differential growth rates of the vertebral column and the spinal cord. This results in a higher termination point of the spinal cord in infants.

**Why the Correct Answer is Right**
In infants, the spinal cord terminates at the level of the third lumbar vertebra (L3). This is because the vertebral column grows more rapidly than the spinal cord during fetal development and early childhood. As a result, the spinal cord appears to be higher in the lumbar region compared to adults, where it typically terminates at the level of L1. The growth of the vertebral column outpaces the spinal cord, leading to this anatomical variation.

**Why Each Wrong Option is Incorrect**
**Option A:** A is incorrect because the spinal cord in infants does not terminate at the level of L1, which is the typical termination point in adults due to the differential growth rates of the vertebral column and the spinal cord.

**Option B:** B is incorrect because the spinal cord in infants terminates at L3, not L2. This is a result of the faster growth rate of the vertebral column compared to the spinal cord during fetal development and early childhood.

**Option D:** D is incorrect because the spinal cord in infants terminates at L3, not L4. This is due to the anatomical variation caused by the differential growth rates of the vertebral column and the spinal cord.

**Clinical Pearl / High-Yield Fact**
For clinical purposes, it is essential to remember that the spinal cord in infants is higher in the lumbar region compared to adults. This anatomical variation is crucial for medical professionals to consider when performing lumbar punctures or other spinal procedures in pediatric patients.
