Who was the prefect when Harry first arrived at Hogwarts?

1. Percy Weasley 2. The fifth part Harry Potter and the Order of the Phoenix 3. Make a prefect's box, listen to the professor's order, and patrol the carriage 4. Bill weasley, Charlie Weasley, Percy Weasley 5. Guide the freshmen and tell them some school rules. 6. Hermione got "excellent" grades in all subjects except Defense Against the Dark Arts (ordinary wizard level). She should be good at arithmetic divination, metamorphosis and magic. 7. Ron failed the O.W.Ls exam and the history of magic. 8. Harry doesn't like Potions, Divination and defence against the dark arts taught by Umbridge. 9. Bulgarian Quidditch team, an internationally renowned star, 10. The fourth one killed Cedric, and the seventh one killed Fred, Colin and other Harry's classmates. Personally, the answer is good.
