Question

the four major types of carbon - based molecules are:
proteins, enzymes, water, and oxygen
carbohydrates, lipids, proteins, and nucleic acids
dna, rna, glucose and starch
fats, oils, sugars, and hormones.

Explanation:

Carbon - based molecules are also known as organic molecules. Proteins are made of amino acids, lipids include fats and oils, carbohydrates are sugars (like glucose) and starches, and nucleic acids are DNA and RNA. Enzymes are a type of protein, water (\(H_2O\)) and oxygen (\(O_2\)) are not carbon - based. DNA and RNA are nucleic acids, glucose is a carbohydrate, starch is a carbohydrate polymer, but this option does not cover all four major types. Fats and oils are lipids, sugars are carbohydrates, hormones can be proteins or lipids, but this option is not comprehensive.

Answer:

Carbohydrates, lipids, proteins, and nucleic acids.
