A student is writing a paragraph about "Broken Chain" and makes the point that Alfonso will go to great lengths to improve his appearance. Which detail from the story would best illustrate this point?

He wants “cuts” like the “Aztec warrior standing on a pyramid.”
He thinks he would look good with “his hair razored into a V in the back.”
He spends hours in front of the mirror “trying to herd his teeth into place.”
He polishes his bike until it gleams “like a handful of dimes.”
