The speaker is Holden Caulfield, the narrator of the cult novel "The Catcher in the Rye", by recluse writer J.D. Salinger. Holden is a teenager who escapes a boarding school in order to spend a few days in New York, where he interacts with strangers and experiences new things.
Meaning and context: When Holden says he has Jane Gallagher on the brain again, he means he cannot stop thinking about her. Jane is a girl whom he deeply admires, but at the same time he never makes the first move. When he learns his roommate has a date with Jane, he is assaulted by jealousy. The complete quote goes like this:
"All of a sudden, on my way out to the lobby, I got old Jane Gallagher on the brain again. I got her on, and I couldn't get her off."

Answer:
A.) to endear certain characters to us.
D.) to show characters’ educational levels.
Stowe's use of dialogue enriches the setting of the story in various ways. First of all, it makes the characters more realistic and endears certain characters to us. By representing their speech as it most likely sounded in real life, we feel like we get to know the characters better. This makes us care about them more deeply. Stowe also uses dialect in order to show the educational levels of the characters, as "standard" English is most likely to be used by characters who are literate and have received some education.
