Similar effects of alcohol are produced by barbiturates & benzodiazepines by acting on GABA-A receptors and these effects are sedation & hynosis

B) prevents depolarization of the next neuron

Antiepileptic drugs such as \"phenytoin\" is going to block depolarization in next neurons result in lowering of epileptic seizures due to blockade of Na+ into the neurons

C) makes it real easy for depolarization to occur

Drug that makes it real easy for depolarization to occur in succinylcholine and acetylcholine by acting on the cholinergic receptors of autonomic ganglia
