What emotional state is Leslie experiencing while deliberating about the dance invitations?

Leslie's emotional state of being overwhelmed by pressure suggests that she is facing significant stress regarding the decisions she needs to make about the dance invitations. This could stem from various factors, such as the desire to please others, fear of social judgment, or anxiety about the repercussions of her choices. Feeling overwhelmed indicates that Leslie might feel burdened by the expectations placed upon her, leading to difficulty in making a decision.

The other responses imply different emotional experiences that do not align with the specifics of someone feeling overwhelmed. Excitement about choices indicates a positive anticipation which contrasts with the sense of being pressured. The fear of making a mistake suggests a cautious state, but does not encompass the broader sense of pressure Leslie might be experiencing. Finally, indifference to social events would imply a lack of concern or interest, which contradicts the notion of being overwhelmed by invitations and decisions. Thus, the correct answer captures the weight of emotional turmoil associated with decision-making in a social context.
