b. the mere exposure effect.
c. deindividuation.

e. the foot-in-the-door phenomenon.

D. self-fulfilling prophecies.

Explanation:

According to my research on studies conducted by various sociologists, I can say that based on the information provided within the question The Piropian's response best illustrates the danger of a self fulfilling prophecy. This is a phenomenon where an individual predicts something will happen, and this “prediction” comes true only because the individual aligns their behaviors in a way that causes that prediction to come true. Just like in this case The country of Superlia believed that Piropia would increase their military so they increased theirs first, which in term caused Piropia to respond by doing the same.
