They allow the body to react to stimuli.

Explanation: Nerve cells (neurons) detect and transmit electrical signals so the body can sense and respond to internal and external stimuli. The other options refer to functions of different cells — chemical exchange at membranes/blood vessels, oxygen transport by red blood cells, and movement by muscle cells.
