Quizplus · Accepted Answer

Carbon and oxygen make up the majority of the human body's organic molecules, including carbohydrates, lipids, and proteins. These molecules form the basic building blocks of cells and tissues, and thus make up a significant portion of body weight. Sodium and chlorine (A) are important electrolytes, but only account for a small portion of body weight. Phosphorus and magnesium (C) are important for bone health and enzyme function, but are present in smaller amounts than carbon and oxygen. Potassium and iodine (D) are essential minerals, but do not make up as much of the body's organic molecules as carbon and oxygen.
