Final answer:
In the 'Harry Potter' series, Professor Moody put Harry under the Imperius Curse multiple times until Harry learned to resist it. The correct option regarding the effect on Harry is that he resisted the curse, not that he cast a counter-curse, fell asleep, or made the curse permanent. Option a is the correct answer.
Step-by-step explanation:
The passage you referenced involves Harry Potter’s experiences in the wizarding world, which addresses the student's question about the effect of the Imperius Curse in this fictional context. In the 'Harry Potter' series, Professor Moody, actually the imposter Barty Crouch Jr. in disguise, puts students under the Imperius Curse to teach them to resist it. Harry experiences this firsthand, and through sheer willpower and self-awareness, he gradually learns to fight the effects of the curse. This forms an essential part of his Defense Against the Dark Arts education at Hogwarts School of Witchcraft and Wizardry.
The Imperius Curse is one of the Unforgivable Curses in the 'Harry Potter' universe and is known for its ability to control the actions of the victim. The text specifically from 'Harry Potter and the Goblet of Fire' describes how Harry resisted the curse with repeated exposure. The process did not involve casting a counter-curse, falling into a deep sleep, or the curse becoming permanent.
Therefore, the correct option in relation to the effects of the Imperius Curse on Harry, as taught by Professor Moody, is a) Harry resisted the curse.
