(C) Deoxyribose sugar is present in the nucleic acid that is represented in the diagram (Picture attached).
Sugar in a nucleic acid can come in one of two forms: either ribose or deoxyribose. The only way to tell which form of sugar is present in a given nucleic acid is by using one of the following methods:
The strand is single-stranded, as is characteristic of RNA, rather than double-stranded, as is characteristic of DNA.
The existence of the nitrogenous base uracil is another piece of evidence that points in the direction of the conclusion that the molecule in question is a polynucleotide strand form of RNA. RNA solely contains uracil, whereas DNA contains thymine.
Thus, the nucleic acid in the diagram contains deoxyribose sugar.
