Deoxyribose, phosphate group, and cytosine and this because the "D" in DNA means that it is composed of the sugar Deoxyribose. note:Deoxyribonucleic acid. Also if you look at the other choices uracil is a base for RNA (Ribonucleic acid) and seeing as how ribose is apart of RNA also and not DNA it couldnt be the answer.
