Final answer:
A 100g carton of yogurt is considered less than half a serving based on the reference of an 8 oz serving size. Hence, the closest answer is 1 serving. The correct option is A).
Step-by-step explanation:
The question is asking how many food guide servings are in a 100g carton of yogurt. Based on the provided information, a similar food item listed is an 8 oz (approximately 227g) yogurt, which is considered 1 serving.
To determine the number of servings in a 100g carton of yogurt, we compare it to this standard serving size. Since 100g is less than half of the 227g serving size for yogurt, the 100g carton would approximately be less than half a serving.
Therefore, the closest answer would be (A) 1 serving, although it is slightly less than a full serving based on the standard referenced. Option A) is the correct one.
