Hint: In vertebrates, the neural system consists of two parts i.e. Central Nervous System and Peripheral Nervous System. The nervous system is the part of an animal’s body that coordinates its behavior and transmits nerve signals between different body areas.
Complete answer:
A. Dendrite- Dendrites or dendrones resemble the branches of a tree are an extension of the nerve cell that propagate electrochemical stimulation received from other nerve cells to the cell body (i.e. they are designed to receive the communication signal from other cells ).
B. Synapse- Synapse is also known as a neuronal junction, as they connect two neurons. They are the site of the transmission of electric nerve impulses or chemical signals between the two neurons. It contains a small gap that separates neurons.
C. Axon- Axons are also known as nerve fibre which is a portion of a nerve cell or neuron whose function is to carry nerve impulses away from the cell body. Neurons consist of one axon that connects it with another neuron or with muscle.
D. Impulse- Impulse or nerve impulse also known as an action potential, these are an electrical signal which travels along a nerve channel. Nerve impulse occurs due to the difference in electrical charge across the plasma membrane of a neuron.
The Nervous system's basic unit of communication is the neuron or nerve cell. Nerve cell consists of a cell body including the nucleus, major branching fiber i.e. axon and various smaller branching fibers i.e. dendrites.

So, as we have discussed above the gap between two neurons is called a synapse i.e. the correct option is B.
Note:
In the human body, nerve cells or neurons are the largest cells. The physical gap or space present between two neurons is called the synaptic cleft.
