The answer to your question is D. One serving is generally quite small. When you think about it, 1 1/2 cups of cooked carrots is a lot of carrots, this would be approx 3 servings. Generally 1/2 a cup of most fruits and vegetables is equivalent to one serving. Just remember that vegetables have a lot of volume, so 1/2 cup is really not a lot, making it only one serving.
