The correct answer is: C.Nitrogen base, phosphate group, and pentose sugar

A nucleotide is the basic building block of nucleic acids (like DNA and RNA) and consists of three components:

1.Nitrogenous base: This can be a purine (adenine or guanine) or a pyrimidine (cytosine, thymine in DNA, or uracil in RNA).

2.Phosphate group: This is attached to the sugar molecule and links nucleotides together to form the nucleic acid chain.

3.Pentose sugar: This is a 5-carbon sugar (deoxyribose in DNA, ribose in RNA).
