One challenging MC question

Which of the following is an example of negative reinforcement?
A. grounding a teenager for misbehaving
B. giving a student extra credit for class participation
C. allowing a student to take an extra examination to gain a pass in the subject
D. making a child sit in the corner until they say "I am sorry"

Lets put it this way, I got 42/44 for the multiple choice. Apart from a stupid mistake, this is the only question I got wrong. I know what the answer is now (D), but would like someone to explain to me why it is correct, and why the answer I chose (C) was incorrect.

As the child has been taken away of a aversive stimulas (by sitting in the corner) to strengthen their behaviour and increasing the likelihood of it not occuring again.

Hope that helps.

Well making a child sit in the corner until they say sorry is the only one that seeks to strengthen a behaviour by removing a negative stimulus (which is what a negative reinforcer does).

The third option does remove an unpleasant consequence (which is avoiding failing) but it doesn't say that taking the exam is a desired behaviour that has become reinforced.

I chose 'C' as well!!! I am such an idiot, because I remember in a previous multiple choice question that I did as practice where 'D' was the answer.

Oh and by the way, do you mind linking me to the multiple choice answers if possible?
