Which of the following is a common way writers fill a natural pause in dialogue

The common way a writer fills a natural pause in dialogue is Option B, by describing a character's gestures.

Explanation:

A common way for writers to fill a natural pause in dialogue is to describe the gestures including facial features or some indication of emotion of the people speaking in the conversation. The pauses in dialogue allow you to write descriptions of subtle gestures and elements of any subtext not evident in the dialogue itself. You can use these moments to create tone and atmosphere in your writing. To improve how you compose dialogue you can practice by trying to transcribe some great natural conversations or scripts from your favorite movies. Practice writing in the subtext and tone in the pauses as well.
