Correct answer: D
Option (d) is the correct answer as impulse transmission across an electrical synapse is always faster than that across a chemical synapse.
$\to$ Chemical synapses use chemicals for transmission which are known as neurotransmitters.
$\to$ The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse.
$\to$ In an electrical synapse, the transmission of the impulse occurs in the form of an electrical current from one neuron to the next neuron.
