What is a popular combination side item featured in Domino's deals?

The correct answer highlights that a popular combination side item featured in Domino's deals typically includes two or more side items. This aligns with Domino's promotional strategies, where they often bundle various sides together to create appealing offer combinations for customers. By presenting multiple side items, customers are encouraged to try a variety of options, making the meal more satisfying and enjoyable. This approach also caters to different tastes and preferences, as it allows guests to share and explore multiple flavors during a single order. In contrast, the other options don't reflect the common practice of combining items for promotional deals, limiting customer choices to singular items or focusing only on drinks.
