When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.
So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.
Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.
So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.

The reason for that is the song gets imprinted on the young birds. Have in mind that birds rised alone will sing but the local pattern will not influence the singing of that bird. So if the birds listen an adult male sing they will help the young ones to get their singing as they will serve as the closest reference. Still have in mind that young birds that are alone can also sing but in a different way, not the one proposed by the environment.
