d.)carbohydrates fight disease.

The right answer is B.) Carbohydrates provide energy for living things.

Under the general term of carbohydrates, more commonly called sugars, we find all substances that, once digested, will provide glucose, the basic fuel of our cells. The effects of carbohydrates vary depending on whether they are consumed alone, with other nutrients or in liquid form.

Carbohydrates are the biggest source of energy for cells. It's not the only one. Fats, alcohol and to a lesser extent proteins can also provide energy. Each gram of carbohydrate contains four calories of which 70% are actually used by our body.
