Solution

The correct option is B at the ends of axons only
In a neuron, synaptic vesicles store various neurotransmitters that are then released at the synapse. The release is regulated by voltage-dependent calcium channel. Vesicles are seen at synaptic junctions at the end of axons.
So, the correct option is B.
