I would go with A. Movement in his lower extremities

Answer;

A. Movement in his lower extremities

Explanation;

-The 1st lumbar vertebra or the L1 vertebra is the smallest and most superior of the lumbar vertebrae. As the first vertebra in the lumbar region, the L1 vertebra bears the weight of the upper body and acts as a transition between the thoracic and lumbar vertebrae.

-The lumbar vertebrae contain spinal cord tissue and nerves which control communication between the brain and the legs.
