An audio recording would most likely convey the characters’ actions during this scene with a change in the volume of the characters' voices
Explanation:
This excerpt of a play is written with a lot of changes in tone, it makes general comments and other that may look like inner voice, changes in volume is a technique than clearly help to emphasize what the characters are saying as we naturally use the stress and intonation in our way of speak, so option C is the best answer for this.
Well, we can eliminate B because there are very few plays where they read out the stage directions. This play just by reading it wouldn't be one of them. So, B is now eliminated.
C can be eliminated too. The volume seems to stay calm throughout all of the passage.
