In the context of the Bible, this statement was made by the prophet Nathan to King David, and it was meant to expose David's sin of adultery with Bathsheba and the murder of her husband Uriah. Nathan told David a parable about a rich man who took the only lamb of a poor man to feed his guests, which angered David and made him say that the rich man should be punished. At this point, Nathan told David, "You are the man," meaning that David was the rich man in the story and had committed the same sin of taking what belonged to someone else. This statement made David realize his sin and he confessed and repented. Therefore, the correct answer is that David confessed and asked for forgiveness.
