Model Answer
(D) Axonal end of one neuron to dendritic end of another neuron.
Explanation
The textbook states that at the end of the axon, chemicals are released which cross the synapse and start an electrical impulse in the dendrite of the next neuron. So transmission is always axon → synapse → dendrite (of next neuron). Option D is the only one that correctly identifies both ends.
