Answer: option d. hydrogen bonds between nitrogen base Pairs

Explanation:

DNA is called a Deoxyribonucleic acids, it contains hereditory information in the cell. DNA is located in nucleus of human cell. DNA consist of nucleotide strands that comprises of a sugar and oxyribose bound on a partto a phosphate group and bound on the other part to a nitrogenous base. The Nitrogenous base consist of Adenine, thymine, guanine and cytosine which are complementary base Pairs. They are grouped into 2 distinct classes called purines (double-ringed structures) and pyrimidines (single-ringed structures). The nitrogenous bases forms a ladder and pairs with bases on the other side commonly called rungs. Each complementary nucleotides purine with pyrimidine are held together by hydrogen bonds. A hydrogen bond is a known as chemical bond that is relatively weak and occurs only between hydrogen atoms along with or and electronegative atoms, e. g oxygen, nitrogen e. t. c. Hydrogen bonds usually occur in short length or distances and are formed quickly or easily and ca also broken.
