The correct answer is by using character actions to create conflict.
In the excerpt, the contrasting behaviors of Mr. Bingley and Mr. Darcy create tension and set the stage for conflict. Mr. Bingley's amiability and sociability contrast sharply with Mr. Darcy's prideful and aloof demeanor, which raises the feelings of resentment among the other characters, particularly Mrs. Bennet. This dynamic highlights the conflict between social expectations and personal pride, which is central to the plot of the novel.
