The space between neurons is called​

A) ​an interneuron.
B) ​an intraneuron.
C) ​a neurotransmitter.
D) ​the synaptic cleft.

The space between neurons is known as the synaptic cleft, which is where neurotransmitters are released and received by the next neuron. Option A is incorrect because an interneuron is a neuron that transmits impulses between other neurons. Option B is incorrect because there is no such thing as an intraneuron. Option C is incorrect because a neurotransmitter is a chemical messenger that is released by the neuron and travels across the synaptic cleft to bind to receptors on the next neuron.
