"Take after" is a common idiom used when talking about family likeness. It means to look like or behave like an older relative, usually a parent.
- Option A, "Idolize": To idolize someone means to admire them greatly, which is about feelings, not physical or behavioural likeness, so it does not match.
- Option B, "Resemble": This is the exact sense of "take after". The children share features or habits with their father, which is what the sentence describes.
- Option C, "Disagree": This means to have a different opinion, which has nothing to do with family resemblance.
- Option D, "Misunderstand": This means to get someone's meaning wrong, again unrelated to looking or acting like a relative.
The correct choice is option B, "Resemble".
