Step-by-step explanation:
Food Sources of Carbohydrates
Foods such as grains, vegetables, fruits, beans, and sugary sweets are rich in carbohydrates. However, the food item from the choices given that does not contain carbohydrates is D. Egg. Eggs are composed mainly of proteins and fats, and contain very little to no carbohydrates. On the other hand, a tortilla is made from flour or corn, both of which are carbohydrate sources. Broccoli, although a vegetable, also contains carbohydrates, albeit in smaller quantities. Lentils are legumes, and they are known to be high in carbohydrates as well. Particularly for athletes, carbohydrate-rich foods are significant because they are easily digested and supportive of high performance. Foods like bread, pasta, and potatoes are staple examples of high-carbohydrate foods that are a common part of sports nutrition.
