Explanation / Answer

Answer: Option A is correct.
Explanation:
The sympathetic division is also called as the thoracolumbar division even though its ganglia extend from the cervical region to the sacral region because sympathetic fibers contain their reflex centers in the spinal cord (in segments T1 to L2).
Their cell bodies are located in the lateral horns of the thoracic segments.
