The discussion of children's metamemory examined research by Roebers and her colleagues. This research asked 5-10-year-old children to judge whether they had answered memory questions correctly. The results showed that

A) these children were much more confident about the questions they answered correctly compared with the questions they answered incorrectly.
B) these children were equally confident about the questions they answered correctly and the questions they answered incorrectly.
C) these children were overconfident about the questions that they had actually answered incorrectly.
