The correct answer is option 4: All of the above.

Option 1: Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms. They are an important source of energy for living organisms and are found in all life forms. Carbohydrates are essential for various biological processes and play a crucial role in cell structure and function.

Option 2: Proteins are complex macromolecules made up of amino acids. They perform a wide range of functions in living organisms, including structural support, enzyme catalysis, transportation, and immune response. Proteins are found in all life forms and are vital for their survival.

Option 3: Nucleic acids are biomolecules that store and transmit genetic information. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are two types of nucleic acids. They are present in all life forms and play a central role in the inheritance of traits and the functioning of cells.

Therefore, all life forms contain molecules of life, including carbohydrates, proteins, and nucleic acids.
