Answer:
deoxyribose + phosphate group + thymine
Explanation:
This question is testing whether you know the differences between DNA and RNA
A DNA nucleotide is made up of deoxyribose. The clue is in the name Deoxyribonucleic acid. The sugar in RNA, is ribose (ribonucleic acid).
The DNA nucleotides are adenine (A), thymine (T), guanine (G) and cytosine (C). The RNA nucleotides are almost the same, except thymine is replaced with uracil (adenine (A), uracil (U), guanine (G) and cytosine (C)).
The only option that has both deoxyribose and thymine (as opposed to ribose and uracil) is the first option, deoxyribose + phosphate group + thymine
