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?

The point is that Alfonso will go to great lengths to improve his appearance. Spending hours in front of the mirror trying to straighten his teeth shows sustained effort to change how he looks. Choice C gives the clearest example; the other choices describe styles he wants or an effort to polish his bike, not hours spent improving his appearance.
