a short; near effectors
b long; near the vertebrae
c long; near effectors
d short; near the vertebrae

Explanation:

Sympathetic preganglionic neurons are short. Their cell bodies are in the lateral horn of the spinal cord (T1 - L2). They synapse with ganglionic neurons in ganglia that are located near the vertebrae (sympathetic chain ganglia, prevertebral ganglia). Parasympathetic preganglionic neurons are long and synapse near effectors.
