Correct Answer
BNephron
CCerebrum
DCerebellum

Solution

A neuron is an electrically excitable cell. It is the functional and structural unit of the nervous system. It processes and transmits information through electrical and chemical signals. These signals between neurons occur via synapses, specialized connections with other cells. Neurons connect to form neural networks. Neurons are the core components of the nervous system.
Hence the correct option is A.
