Incorrect Statements about Electrical Synapse:

Membranes Proximity:
- Statement (i) is incorrect because at electrical synapses, the membranes of pre and post synaptic neurons are in direct contact, not just in close proximity.

Direct Current Flow:
- Statement (ii) is correct as electrical current can flow directly from one neuron into the other across the synapses.

Impulse Transmission:
- Statement (iii) is incorrect as the transmission of an impulse across electrical synapses is not similar to impulse conduction along a single axon. It is faster and more direct.

Use of Ach:
- Statement (iv) is incorrect because electrical synapses do not pass electrical signals between cells using acetylcholine (Ach) or any other neurotransmitter.

Speed of Transmission:
- Statement (v) is correct as electrical synapses are known for their fast transmission of signals between neurons.

Prevalence of Electrical Synapses:
- Statement (vi) is incorrect as electrical synapses are actually quite common in the nervous system, especially in regions where rapid signaling is essential.
Therefore, the incorrect statements about electrical synapses are (i), (iii), and (iv), making option (c) the correct choice.
