At the end of an axon we find?
A
Action
B
Dendrites
C
Axon terminals
D
Synapse
Explanation: 

Detailed explanation-1: -Axon ends in axon terminals. Axon terminals are closely placed near the dendrites of another neuron or more neurons but are not connected. Cyton is the cell body of the neuron. The axons of the neurons are surrounded myelin sheath that shows gaps throughout the length that are called nodes of Ranvier.

Detailed explanation-2: -At the end of an axon, there is a so-called axon terminal that is button-like and is responsible for providing synapses between neurons. The axon terminal contains specialized chemicals called neurotransmitters that are initially contained inside the synaptic vesicles.

Detailed explanation-3: -And each axon terminal has an output receptor at the end of it known as a synaptic terminal. The synaptic terminal transmits chemical messages and release neurotransmitters onto other cells. The space between the synaptic terminal and the input receptor of the next cell is known as a synapse.

Detailed explanation-4: -The Axon terminal ends in a synaptic knob. When the impulse reaches the axon terminal, it triggers the movement of synaptic vesicles towards the membrane where it fuses with the plasma membrane releasing its neurotransmitter in the synaptic cleft.

Detailed explanation-5: -Axon terminals transmit chemicals from one neuron to another. They are positioned at the opposite end of the neuron to the dendrites.
