Because marion thinks peter is unfriendly, marion has never waved or said hello to peter when she sees him in the hall, who is shy, has not greeted marion either. his lack of greeting has reinforced marion's belief that he is unfriendly. it appears as if marion's behavior has let do which of the following?

a. self-fulfilling prophecy
b. self-serving bias
c. false consensus effect

a. self-fulfilling prophecy

Explanation:

In psychology, a self-fulfilling prophecy refers to the phenomenon where  someone "predicts" or expects something, and this “prediction” or expectation comes true simply because one believes it will, and therefore the resulting behaviors align to fulfil those beliefs. In other words, a false expectation leads to its own confirmation, so the false expectations of a person eventually lead the other person to behave in such way that it confirms the original expectations.

In this example Marion thinks Peter is unfriendly and she never says hello. Peter is shy and doesn't say hi either. This lack of greeting reinforces Marion's belief that he is unfriendly. We can see that Marion has a false expectation about Peter (he is unfriendly) and since she doesn't say hi, he doesn't say hi either, therefore, this leads Marion to "confirm" that Peter is unfriendly since the behavior of him not saying 'hi' align to fulfill this belief. Therefore, this is an example of self-fulfilling prophecy.

a. self-fulfilling prophecy

Explanation:

A self-fulfilling prophecy is a false expectation that we have about someone and because we have this false expectation people start to seem like they are actual behaving exactly as we have predicted and our prophecy is confirmed. It can also be explained as a belief that we have about something and when this belief comes true then our prophecy is confirmed.

For example Marion thinks Peter is unfriendly because he had never waved at him , this is his prophecy, what he believes is true so a shy Peter actual does that because he is shy but for Marion this is a confirmation of what he thought and predicted about about Peter so his prophecy is fulfilled.
