In the prologue of oedipus rex, Creon returns from delphi with a command from the oracle to find and punish the murderer of laius.

Explanation:

The king of the city Thebes, Oedipus sends Creon to the Oracle. The citizens of Thebes face a terrible fate in the form of plague. So, to find an end to it, Oedipus sends Creon for seeking a solution. He returns with a message to drive the Laius’s murderer out.

He insists that the murderer is staying in Thebes, and exiling him off the land will turn the city to a normal state. Therefore, Oedipus warns the people who are supporting the murderer and asks them to hand him over to the king.

given the fact that the question is about the detail that best support the idea that oppressive leaders use   propaganda to achieve thir goals,   the first option does not refer to any kind of propaganda, since it only tells about that the milk and the windfall apple should be reserved for the pigs. in the second option, that is, "snowball and napoleon sent out flights of pigeons whose instructions were to mingle with the animals on the neighbouring farms, tell them the story of the rebellion, and teach them the tune of "beasts of england". it can be identified that the oppressors make use of the propaganda, which is represented by the pigeons, and the information they have to tell other animals about what was happening in the farm in order to get their objectives. for that reason, the right answer is the second option, taking into account that the third option do not refer to propaganda since it only talks about that they did not want jones back. and, finally, the last option refers to the result of the given news, but it does not mean about the propaganda they used to achieve their goals.
