Answer: (C)

Verified step by step guidance

1. Understand the structure and function of proteins: Proteins are large, complex molecules that play many critical roles in the body. They are made up of one or more chains of amino acids.
2. Identify the building blocks of proteins: Proteins are composed of amino acids, which are organic compounds that combine to form proteins. Amino acids are the building blocks of proteins.
3. Differentiate between the options given: Fatty acids are building blocks of lipids, nucleotides are building blocks of nucleic acids, and monosaccharides are building blocks of carbohydrates.
4. Recognize the role of amino acids: Amino acids link together in specific sequences to form polypeptides, which fold into functional proteins.
5. Conclude that amino acids are the correct answer: Based on the understanding of protein structure, amino acids are the fundamental building blocks of proteins.
