Which piece of evidence BEST supports the idea that Aucouturier's audio tool could revolutionize voice research?

A Aucouturier and his fellow scientists developed a new audio platform specifically for this experiment, where they could input a participant's voice, modify it and then play it back to the person — all within a moment's time.

B This created the illusion that the participant was hearing their normal voice speak through headphones. It usually takes just 1 or 2 milliseconds for us to "hear" our own voice.

C Only 16 said they could tell that their voice had been modified, and their results were removed from the final findings, according to Aucouturier.

D But in this experiment, the majority of participants were unaware. Where psychological research is concerned, "we could be looking at the ultimate tool for emotion regulation here."
