Answer:
O A. An army of redheads, angry at having been exiled, returns and overthrows the king.
Explanation:
In the given scenario, the new King banished all the red-heads as a precaution against losing his throne/ kingdom. This is perfectly reasonable, considering his kingdom is on the line and also to make sure that the prophecy of the old woman does not come true.
But in that act of banishment, it will lead to an angry group of red-heads that will want to get their revenge. Eventually, all the banished red-heads will return, forming an army to fight any resistance from the king and with the hope of overthrowing the king. Moreover, with the overthrow of the king, the prophecy that a red-head will take his crown becomes fulfilled.
Thus, the most logical conclusion is option A.
