A
an amino acid
B
a phosphate group
C
a carbon group
D
a nitrogen base
Explanation: 

Detailed explanation-1: -Nucleotides that make the DNA strands contain deoxyribose sugar, phospate molecule and one nitrogenous base out of adenine, guanine, thymine and cytosine. Uracil is never a part of nucleotide of DNA.

Detailed explanation-2: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).

Detailed explanation-3: -Answer and Explanation: The statement that is true about the structure of nucleotides is (a.) Composed of 1 phosphate, 1 nitrogen base, and 1 sugar. Nucleotides are the primary building blocks of the nucleic acids, DNA and RNA.
