As fire when thrown into water is cooled down and put out, so also
false accusation when brought against a man of the purest and he
character, boils over and is at once dissipated, and vanishes and
threats of heaven and sea, himself standing unmoved.
what do you think the quote above means?

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.

" animal is healthy and eternally gratefully that you provided him with a warm home." and "the health and well-being of our animal friends is what is at stake here."
