Final answer:
Malfoy tricked Harry by challenging him to a duel and not showing up, intending to get Harry into trouble for roaming the school at night.
Step-by-step explanation:
In the Harry Potter series, Malfoy tricked Harry after challenging him to a wizard's duel by not showing up, which was not one of the options provided in the multiple-choice question. Instead, Malfoy deliberately misled Harry, intending to get him in trouble for being out of bed at night.
This is different from the excerpt provided from the book, which describes Harry's first encounter with Voldemort, an unrelated event where they find a dead unicorn and witness a hooded figure drinking its blood.
