What item is categorized under kids and extras?

The correct answer is scramble egg, as it is categorized under kids and extras on the menu. This classification generally includes items that are appealing to children or can be added to a kid's meal to enhance its value. Scrambled eggs are a common option for kids due to their soft texture and protein content, making them a nutritious choice for younger diners.

In contrast, milk, decaf coffee, and Simply Orange juice serve different purposes within the menu and are not primarily intended for children as standalone items. Milk may sometimes be included in kids' meals but is more of a beverage choice for all ages rather than a specific food item meant for children. Decaf coffee is oriented towards adult customers seeking a caffeine-free option, and Simply Orange juice is typically considered a beverage rather than a food item.
