The correct option is C Axonal end to the dendrite through synapse
The electric pulse in a neuron is received from the dendrite and then passed further. When the pulse reaches the axonal end it has to transfer to another neuron this takes place through the gaps present between the axon of one neuron and dendrite of the next neuron called synapse. Synapse help in the flow of impulses throughout the neuron network. Therefore, the correct answer is option B.
