Correct Answer: B

Rationale: The best snack choice for a preschool-age child is a mini wheat bagel with peanut butter as it provides a good balance of carbohydrates, protein, and healthy fats. Fruit snacks, although they contain some fruit flavor, are often high in added sugars and lack essential nutrients. White toast with jelly may provide quick energy but lacks protein and healthy fats, which are important for a balanced snack choice. Sports drinks are typically high in sugar and unnecessary for a preschool-age child's snack, as they are designed for rehydration during intense physical activity, not as a regular snack option.
