What might influence the selection of sides for a customer's order?

The correct answer is centered around the understanding that personal taste preferences and dietary restrictions play a significant role in influencing a customer's selection of sides. Customers often choose sides based on their individual likes and dislikes, which can vary widely from one person to another. For example, someone who is vegetarian might opt for a side salad or stuffed cheesy bread, while another customer may have a preference for wings or cheesy breadsticks.

Moreover, dietary restrictions, such as allergies or health-related choices, can further dictate what customers will select. A person who is lactose intolerant, for example, would avoid sides that contain cheese. This awareness of individual needs and wants ensures that customers feel satisfied with their choices, enhancing their overall dining experience.

While promotional pricing can attract customers, it is not the primary driver of choice compared to personal preferences and dietary needs. Similarly, the number of people ordering may influence quantity rather than the selection itself, and ingredient availability is more of a logistical factor than a direct influence on personal choice. Understanding this dynamic highlights the importance of catering to the unique tastes and restrictions of each customer, making option B the most accurate choice in this context.
