The component of nerve cells that contains the nucleus is the cell body.
The correct answer is the cell body. The cell body, also known as the soma or perikaryon, is the main part of a nerve cell that contains the nucleus. It serves as the control center of the cell, housing the majority of the cell's organelles and controlling its metabolic activities. The axon, dendrites, and neuron are all other components of a nerve cell, but they do not contain the nucleus.
