Sometimes they can appear in the same sentence, or they can come later. For this purpose, the author can use a synonym, an antonym, an example or an explanation.

B). To help deduce the meaning of an unfamiliar word.

Explanation:

Context clues are demonstrated as the clues or hints that assist the readers to deduce or define the meaning of an unfamiliar word employed by the author. These clues are provided to clarify the meaning of the unusual words and the context in which they've been used by the author. These clues appear usually in the same sentence or the sentence followed by it. These clues may include synonyms, antonyms, an elaboration, or some particular illustrations to reflect or clarify the meaning. Thus, option B is the correct answer.

explanation:

the excerpt from chapter 2 of "animal farm", by george orwell that is an example of foreshadowing is "these three (snowball, napoleon, and squealer) had elaborated old major's teachings into a complete system of thought to which they gave the name of animalism." animal farm is an allegory of how czarist russia developed into communist russia with all its corruption. old major's teachings represent marx's theories turned into communism, animalism, by the three pigs. this foreshadows the oppression and corruption that will follow this revolt.
