Answer:
C) rationalization
Step-by-step explanation:
Rationalization is a form of defense mechanism in which an individual tries to use their own facts, which are really not true, to explain why certain unpleasant situations occur or to explain an undesirable behavior.
From the scenario given about the girl in the question who was not invited to the school dance, the defense she put up as a reason for not being invited was based on her self created or fabricated facts in order to find an explanation to why she would not have attended the dance if invited.
