It is carbon because its used to build macromolecules
Carbon is the element used in organisms as a storage compound, for cell formation, and to build macromolecules due to its ability to form stable bonds with many elements.
Among the elements listed, Carbon is the one most commonly used in organisms as storage compounds, in cell formation, and to build macromolecules. Carbon forms the backbone of complex molecules such as proteins, nucleic acids, carbohydrates, and lipids, all of which are essential for life processes. While elements like Nitrogen, Hydrogen, and Phosphorus also play vital roles in living organisms, it is Carbon's versatility and ability to form stable bonds with many other elements that make it indispensable in the formation and function of macromolecules.
