Explanation:
Deoxyribose nucleic acid or DNA is a type of nucleic acid which acts as genetic material in the organisms.
Each strand of DNA is made up of nucleotide which is made up of a 5 carbon sugar called deoxyribose, a phosphate group and 4 types of nitrogenous bases mainly adenine, thymine, guanine and cytosine. The sugar and phosphate form the backbone of the DNA molecule while the nitrogenous bases are stacked perpendicular to the backbone.
Thus, option- deoxyribose, thymine, and a phosphate group.
