Answer:
B. Describing a character's gestures.
Explanation:
One of the ways in which writers often fill a natural pause in a dialogue is by describing a character's gestures. This serves two purposes. On the one hand, this allows the author to elaborate on the character's feelings and reactions without the need to use more words. Another advantage is that this allows the writer to create a more natural conversation, as people often speak in this way in real life.
