The correct option is B) send chemical messages across small gaps between neurons.

Explanation:

Neurons are the cells that make up our nervous system. Although they are connected to each other, they do not maintain physical contact with each other. The nerve impulse travels through the neuron, and when it reaches its dendrites, it is transmitted to the next neuron through the synapse, which is produced through the exchange of chemical substances called neurotransmitters. Neurons communicate with each other through the small spaces (or small gaps) between them, in a process known as synaptic transmission (where synapses are the connections between neurons). This synapse requires neurotransmitters (for example dopamine or glutamate) for the transmission of the signal or message, which after being released will bind to specific receptors causing an ionic change by opening or closing a channel.
