Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R). 
Assertion (A): Impulse transmission across an electrical synapse is always faster than that across a chemical synapse.
Reason (R): Neurotransmitters released at electrical synapses quickly diffuse through synaptic cleft and bind to receptors, present on the post-synaptic membrane leading to the generation of new potential in the post-synaptic neuron.
In the light of the above statements, choose the most appropriate answer from the options given below.

Detailed Solution

(A) is correct. Impulse transmission across an electrical synapse is always faster than that across a chemical synapse. Electrical synapses allow for direct electrical coupling between neurons through gap junctions, enabling faster transmission of signals compared to chemical synapses.

(R) is not correct. Neurotransmitters are released only at chemical synapses, not at electrical synapses. In electrical synapses, the transmission is through direct flow of ions via gap junctions, without the involvement of neurotransmitters.
