Answer:
B: to emphasize the father's determination to find help for his son.
Explanation:
The author's main purpose for including these words spoken by the father is to emphasize his determination to find help for his son, and there are some words or phrases in them that seem to express this idea, such as "..I'll find somebody to take care of you."; "..there's a doctor...I'll take you to him."; "I've carried you for hours, and I'm not going to leave you lying here..."
No matter how wealthy they may be it doesn't give them happiness.
This passage uses repetition to create a haunting effect in two different ways. The first way repetition is used is through literal repetition, repeating the phrase "my darling" and ending both of the final lines with the word "sea". The second form of repetition that creates this effect is the repetition of an idea. A sepulchre is an area where a person is buried, and so is a tomb, so the final two lines have the same meaning.
The change in end rhyme in from the first two lines to the last two lines is also significant, because it changes the focus of the poem from mourning the person who has been laid to rest, to the place in which she has been laid to rest.
Alliteration is probably the thing you're looking for
