The correct option is B

CNS


Spinal cord is a part of CNS [Central Nervous System] along with brain. It’s the centre for all involuntary, sudden actions or reflexes which do not involve prior thinking. Peripheral nervous system is the network of neurons [cranial and spinal nerves] which have specific functions. ANS [Autonomic nervous system] also regulates certain involuntary actions of visceral organs through sympathetic and parasympathetic nervous system.
