What is the correct mixture for Denny's green smoothie?

The correct choice features a blend that aligns with the flavor profile and texture typical of Denny's green smoothie. The inclusion of 5 oz of mango provides a rich sweetness and fruity flavor that forms a solid base for the smoothie. The use of 2 oz of vanilla introduces creaminess and a smooth texture, enhancing the overall mouthfeel and making the smoothie more enjoyable without overpowering the other flavors. The addition of 1/4 banana adds a slight earthiness and thickness, contributing to the smoothie’s consistency, while the pinch of spinach offers the essential green component that gives it the "green smoothie" characteristic, along with a hint of nutritional value.

This combination strikes a balance between sweetness, creaminess, and the subtle earthiness that spinach provides, creating a harmonious and appealing drink. The other options do not achieve this balance as effectively, resulting in mixtures that might not match the expected flavor and texture characteristics of Denny's green smoothie.
