What purpose does Lisa serve in the narrative regarding Burl's business?

Lisa serves to foreshadow Burl's anxiety in his business by highlighting the emotional and psychological aspects of his involvement in that venture. Through her interactions, remarks, or the challenges she presents, the narrative conveys a sense of tension or uncertainty that reflects Burl's own state of mind regarding his business decisions. This use of characterization creates a deeper understanding of how external influences, such as Lisa’s presence or behavior, mirror and amplify Burl’s internal struggles with anxiety and pressure connected to his entrepreneurial journey.

The other options, while potentially relevant, do not accurately capture Lisa's primary function in the narrative as effectively as highlighting the foreshadowing of Burl's anxiety does.
