Final answer:
In Asch's study on conformity, the person least likely to conform to a unanimous majority in a similar situation would be someone who has a single ally who dissents from the incorrect majority opinion.
Step-by-step explanation:
In Asch's study on conformity, the participants were presented with a series of line judgments and had to give their answer after hearing everyone else's response. The question asks which of the following people would be least likely to conform to a unanimous majority in a similar situation. Based on Asch's findings, the person least likely to conform would be someone who has a single ally who dissents from the incorrect majority opinion. When even one person in the group dissents, the subject is much less likely to conform.
