The best example of foreshadowing is D) "When they came back in the evening it was noticed that the milk had disappeared".
<em>Foreshadowing</em> in literature refers to a hint given by the author about something that will happen later in the novel. This episode of <em>Animal Farm</em> (1945) is significant because it foreshadows the pigs’ eventual abuse of power by implying they kept the milk for themselves instead of sharing it with the other animals in the farm. In that way, the pigs' conspiracy shows they believe to be superior than the rest of the animals and; therefore, to have the right to exert control over them. Furthermore, the 'disappearance' of the milk foreshadows the pigs' betrayals over the course of the story such as the death of Boxer, the hard-working horse that is sold off and slaughtered.
