Answer:
The correct answer will be option-B.
Explanation:
Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. Each monomer is made up of a five-carbon deoxyribose sugar, a phosphate group and four different nitrogenous bases.
The nitrogenous bases- purines (adenine and guanine) bond with pyrimidines (cytosine and thymine) via hydrogen bond between them. The hydrogen bonds are weak bonds but establish the DNA structure.
Thus, Option-B is the correct answer.
