Answer: Option A.
Telephone conservation.
Step-by-step explanation:
It is telephone conservation because it is analogous to synaptic signalling because it involve a personal conversation between a person who is far away or very distant and both the communicator and the recipient are able to receive message between each other or they are able to communicate their thought which is synonymous to synaptic signalling.
Cells connect to each other to communicate to each other over long distance through these three main ways and they are gap junctions, tight junctions, and desmosomes.
