Which side option features a cheese and bacon topping?

The correct choice features a side option that includes both cheese and bacon toppings, which is specifically highlighted in the menu for bacon cheddar wedges. This option is crafted to combine the rich flavors of melted cheese and crispy bacon, offering a savory and indulgent experience. It appeals to customers looking for a flavorful side that enhances their meal and provides a unique twist on traditional sides.

Other side options listed, such as onion rings, curly fries, and wedges, may have their own unique flavors and textures but do not come topped with both cheese and bacon, making them distinct from the bacon cheddar wedges. Hence, they do not meet the criteria specified in the question regarding the combination of toppings.
