Answer 2

Hi there!

The answer is A. I want to hear everything, but - oh, someone is knocking on the door. In this case, the dash is indicating an interruption and an abrupt change in topic while speaking. All other options can be replaced by commas or the dash can just be removed without any other modifications. 

Hope this helps!
