What are the four molecules of life?
A
carbohydrates, lipids, proteins, nucleic acids
B
water, earth, wind, fire
C
carbon, oxygen, hydrogen, helium
D
monomers, polymers, disaccharides, glucose
Explanation: 

Detailed explanation-1: -Proteins (polymers of amino acids) Carbohydrates (polymers of sugars) Lipids (polymers of lipid monomers) Nucleic acids (DNA and RNA; polymers of nucleotides)

Detailed explanation-2: -There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass.

Detailed explanation-3: -biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.

Detailed explanation-4: -These four essential molecules are classified as proteins, nucleic acids, carbohydrates and lipids. They provide structure and energy to the cells of all living organisms. In addition, these molecules are necessary for the various functions in cells, therefore, they are referred to as fundamental molecules of life.

Detailed explanation-5: -Each of these exists as a polymer, composed of the monomers shown in the table. monosaccharide, disaccharides, and polysaccharides; quick energy for the cell. and a little O. sometimes S.
