Answer:
B. Foreshadowing.
Explanation:
In chapter 1 of Lord of the Flies, when the plane crashes on the unihabited island, Jack, Ralph, and Simon goes to examine the island to know whether the island is truly inhabited or not.
After they get confirmed that the island is unihabited, they have a great jaunt over the granite cliff. While they are having a fun, over the granite cliff, they find a pig caught in the vines. Jacks inability to kill the pig and his vow to kill it next time he sees is an example of foreshadowing.
This foreshadows the death of Simon, who was killed in a zest by the group led by Jack.
Therefore, option B is correct.
