Answer #1

D.Stomach

The thoracic splanchnic nerves originates from sympathetic trunk of trunk and innervates into the abdomen.The preganglionic nerves and general efferent visceral fibers functions upon stimulation. The post ganglionic neurons of sympathetic nervous system are absent in stomach.

Cardiac sympathetic preganglionic nerve originates from the upper thoracic region of the spinal cord and forms the sympathetic chain ganglia through postganglionic nerve extend to the viscera that is heart.To execution of fight and flight mechanism response , pre and postganglionic nerves of sympathetic nervous system works in adrenal gland and lung in order to release epinephrine and incresing breathing rate respectively.
