Which of the following is an appropriate question regarding customer preferences for the Chicken Laredo?

The selection of asking which toppings a customer prefers for the Chicken Laredo is appropriate as it directly engages the customer in customizing their meal experience. This question allows for a tailored dining experience, enabling the customer to choose toppings that suit their individual taste, which can enhance their satisfaction with the dish.

In contrast, the other options either do not specifically pertain to preferences related to the Chicken Laredo or imply choices that are generally less customizable. Asking about spiciness can be relevant but is not as focused on personalization as actual toppings. Inquiries about drinks or dipping sauces can be important but are more related to meal accompaniments rather than the specific modifications to the Chicken Laredo itself. Therefore, addressing toppings provides a more direct influence on the dish itself, aligning closely with customer preferences for that specific menu item.
