Answer:
(c). are gaps between neurons where chemical signals are used to transmit information
Explanation:
Synapses can be defined as junction present between two nerve cells, through which nerve impulses are transmitted by using chemical signals or neurotransmitters. The synapses represent a small gaps that separate two neurons.
