Ribose sugars are found in
A
DNA
B
RNA
C
Proteins
D
None of the above
Explanation: 

Detailed explanation-1: -ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone ‘’ of the RNA polymer and binds to nitrogenous bases.

Detailed explanation-2: -Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).

Detailed explanation-3: -Ribonucleotides consist of a ribose sugar, phosphoric acid, and a nitrogenous base. An example of a ribonucleotide is an ATP (adenosine triphosphate). UTP, GTP, and CTP are other ribonucleotides found in RNA.
