Which passage describes his appearance as unkempt? a: "on a rare occasion he wore a necktie, " it was usually skewed and stained with food or something."b: "he had a way of making even the littlest, most unimportant person on feel important. c: his charisma was impeccable. d: "he could charm the birds out of the trees."
