Which of the following is a side option at Jack in the Box?

Donut Holes are considered a side option at Jack in the Box, as they are typically categorized under the dessert or snack items a customer can choose to accompany their meal. Sides usually consist of items that complement the main course without being a full meal by themselves, and Donut Holes fit well into this category.

On the other hand, Fish Tacos and Beef Tacos are generally regarded as main menu items due to their substantial portions and the fact they are often ordered as standalone meals. Similarly, a Chicken Sandwich is a complete meal item rather than a side.

This distinction between main meal items and sides is crucial when selecting options in a fast-food setting, helping customers to build a well-rounded order tailored to their preferences.
