Answer Key / Explanation : (d) -

(d)

A is correct, but R is not correct.

There are two types of synapses namely electrical synapses and chemical synapses. At electrical synapses, the membrane of pre and post synaptic neuron are in very close proximity transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon
