Ans. (b). Like all eukaryotic cells, neurons have a nucleus that controls the activities of the cell.
Neurons are described as basic structural and functional units of the brain that transfer the information to muscles, nerve cells, or glands from the brain. Each neuron has three parts, dendrites, a cell body, and an axon.
The cell body consists of several important cell organelles, such as nucleus, ribosomes, endoplasmic reticulum, and mitochondria. The main function of cell body is to control and regulate the activity of neurons.
Thus, the correct answer is option (b).
