The right option is; A. carbohydrates
Carbohydrate is the most important energy source for the body and it is the macromolecule that provides a person with most of the energy that is needed for daily activities. The body breaks down and uses carbohydrates faster and easier. This makes carbohydrate a short term fuel source that provides the body's most immediate energy that is required for daily functions. Also the body prefers to use carbohydrate as fuel during some activities such as exercise. Sources of carbohydrate include brown rice, whole grains (barley, and oats), fruits and vegetables and beans.
