Final answer:
The correct components of DNA nucleotides are nitrogenous bases, phosphate group, and deoxyribose, making option A the right answer.
Step-by-step explanation:
The three components of DNA nucleotides are a nitrogenous base, a phosphate group, and deoxyribose, which is a five-carbon sugar. The nucleotide is named depending on the nitrogenous base it contains, which can be a purine such as adenine (A) and guanine (G), or a pyrimidine such as cytosine (C) and thymine (T). Out of the options provided, the correct answer is A) Nitrogenous bases, phosphate group, and deoxyribose.
