Final answer:
According to the USDA's MyPlate guide, half of a plate should be filled with fruits and vegetables, with the rest divided between grains and proteins, accompanied by a serving of dairy.
Step-by-step explanation:
To encourage good nutrition, the MyPlate guide developed by the United States Department of Agriculture (USDA) recommends that half of a plate should be filled with fruits and vegetables. The concept behind MyPlate is to visually help the general public understand the proportions of each food group necessary for a balanced meal.
The other half of the plate is divided into two sections as well, with one quarter being filled by grains (half of which should be whole grains) and the other quarter filled by proteins. Additionally, a serving of dairy, ideally low-fat or non-fat, should accompany each meal.
That being said, the best answer to your multiple-choice question is D - fruits and vegetables.
