Ans. D T1

1. Because the spinal cord stops growing in infancy while the bones of the spine continue growing, the spinal cord in adults ends at about the level of the vertebra L1, and at birth at L3.

2. To get through the intervertebral foramen at the correct segment, the roots must travel down the length of the spine, thus gaining an oblique course.

3. That is why the spinal nerves are more & more oblique as we trace them from supero-inferiorly. For e.g., L-5 spinal nerve is more oblique as compared to T-5.

4. Also, L-5 will be more in length as compared to T-5
