Best way to show somebody getting cut off?

When a character who is talking gets cut off while talking, which example would you most likely use? I'm not sure if this is a dumb question or not, but just wanted to ask for opinions even if it's very minor!

A. "This is going to be good, I'm so glad nobody is interrupting our snack time-"

B. "This is going to be good, I'm so glad nobody is interrupting our snack tim-"
