The correct answer is: C.Neurotransmitters.

Explanation:

Neurotransmitters are chemicals used for communication between nerve cells (neurons) in animals. The communication involves both electrical and chemical signals. An electrical impulse (action potential) travels along a neuron, leading to the release of neurotransmitters into the synapse (the gap between neurons). These neurotransmitters then bind to receptors on the next neuron, transmitting the signal chemically. This combined electrical and chemical process is fundamental to how the nervous system works.
