Answer: (C)

Verified step by step guidance

1. Understand that DNA, or deoxyribonucleic acid, is a molecule that carries genetic information in living organisms and is composed of smaller units called nucleotides.
2. Recognize that nucleotides are the building blocks of DNA. Each nucleotide consists of three components: a phosphate group, a sugar molecule (deoxyribose in DNA), and a nitrogenous base.
3. Identify the four types of nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair specifically (A with T, and C with G) to form the rungs of the DNA double helix.
4. Differentiate nucleotides from other biological molecules such as amino acids, which are the building blocks of proteins, fatty acids, which are components of lipids, and monosaccharides, which are simple sugars and the building blocks of carbohydrates.
5. Conclude that nucleotides are the correct answer as the building blocks of DNA, as they form the structure and sequence that encodes genetic information.
