The answer would most likely be sodium because carbon is a plants food, phosphorus is a nutrient in soil, hydrogen is air, but sodium does not have a place in a plant:)

Answer:

D

Explanation:

Carbon, Hydrogen and Phosphorus are  components of the building blocks of CHO and lipid.

Cellulose is made up of straight chain  d-glucose molecules( un branched) linked together by the beta-1-4- glyosidic bonds.

Phosphorus is present in Lipids as phospholipids, when combined with the lipids in the cell membranes of cells.

Sodium is an extracellular ions of the cells and not in the cell wall or membranes, so D.
