Answer:

Either of them! It depends on what you mean.

“He answered the teacher with confidence” means he answered the teacher confidently; he knew the answer, and he knew he was right.

“He answered the teacher in confidence” means that the teacher had asked him something very personal and private; he was answering the teacher confidentially, and was confident that he could trust the teacher not to pass it on.
