The answer is option C.
In the excerpt from "The Californian's Tale," by Mark Twain, the colorful description is summarized by the next sentence:
"Old Charley arrived about twilight to listen to Henry read the letter, to discuss the party, and to keep his friend from worrying."
Option A is not right because it omits the duscussion. Alternative B is not correct because the men do not talk about past times and the statement does not mention Henry's fears, just like the affirmation in D.
