(B) $DNA$ is a polymer of nucleotides. Each nucleotide consists of a nitrogenous base,a pentose sugar (deoxyribose),and a phosphate group.The phosphate group $(PO_4^{3-})$ is acidic in nature and carries a negative charge due to the presence of hydroxyl groups that release protons at physiological $pH$.Since the phosphate backbone is present throughout the length of the $DNA$ molecule,it imparts an overall negative charge to the $DNA$ structure.
