The sentence should read: "His infatuation for the girl led him astray."
Why "for" is the correct choice:
Collocation: In English grammar, the noun infatuation is almost always followed by the preposition "for" (e.g., "an infatuation for someone/something").
Meaning: It indicates a strong, often short-lived, feeling of intense passion or admiration directed toward a specific object or person.
Why the other options don't fit:
B) about: While we are "passionate about" something, we do not say "infatuation about."
C) in: This preposition does not typically collocate with "infatuation."
D) from: This suggests separation or origin, which does not fit the context of a feeling directed toward a person.
