Verified step by step guidance

Step 1: Understand the structure of RNA (Ribonucleic Acid). RNA is a nucleic acid composed of nucleotides, each containing a phosphate group, a nitrogenous base, and a sugar molecule.

Step 2: Recall that the sugar molecule in RNA is a pentose sugar, meaning it has five carbon atoms.

Step 3: Compare the sugar in RNA to the sugar in DNA. DNA contains deoxyribose, which lacks an oxygen atom at the 2' position of the sugar ring. RNA, on the other hand, contains ribose, which has a hydroxyl (-OH) group at the 2' position.

Step 4: Eliminate the incorrect options. Glucose is a hexose sugar (six carbons) and is not part of nucleic acids. Fructose is also a hexose sugar and unrelated to RNA structure. Deoxyribose is found in DNA, not RNA.

Step 5: Conclude that the sugar present in RNA is ribose, which is essential for the structure and function of RNA molecules.
