Confident, well-behaved children most likely have:

A: Authoritarian parents

B: Permissive parents

C: Abusive parents

D: Authoritative parents

E: Attentive parents

D.

Explanation:

If the parents are authoritative, the child will get the attention it needs and will be confident, and also well-behaved. Here's why the other answers are incorrect.

Authoritarian is incorrect because the discipline methods they use would do more harm than good on the child

Permissive is incorrect because the parents would often ignore the child, making the child have a huge need for attention and lack of care for others.

Abusive is incorrect because the child would be too afraid to speak up because of the childhood experiences they had previously.

I don't believe any of these answers are correct, but the answer I would go with is D.
