The question is asking who expressed regret with the statement "Did not our hearts burn within us while he talked to us..." The options are Peter's audience at Pentecost, the twelve after His audience arrest, Cleopas and one other disciple, or Cornelius and his friends. The correct answer is Cleopas and one other disciple.

In the Bible, after Jesus' crucifixion, Cleopas and one other disciple were walking on the road to Emmaus when Jesus appeared to them, but they did not recognize him. As they walked, Jesus explained to them the scriptures concerning himself. Later, when Jesus broke bread with them, their eyes were opened, and they recognized him. It was at this point that they made the statement "Did not our hearts burn within us while he talked to us..." This statement expresses their regret that they did not recognize Jesus earlier and that they did not fully understand the scriptures until he explained them.

Therefore, the correct option is C: Cleopas and one other disciple. It is important to study the Bible to have a better understanding of its contents and teachings.
