Verified step by step guidance

Step 1: Understand the chemical composition of sugars. Sugars are organic molecules composed of carbon (C), hydrogen (H), and oxygen (O) in a specific ratio of 1:2:1.

Step 2: Recall the definition of monosaccharides. Monosaccharides are the simplest form of carbohydrates and are single sugar molecules that follow the 1:2:1 ratio of C:H:O.

Step 3: Compare the given options. Nucleotides are building blocks of nucleic acids, polysaccharides are long chains of sugar molecules, and lipids are hydrophobic molecules primarily composed of C and H with very little O. None of these match the 1:2:1 ratio characteristic of monosaccharides.

Step 4: Identify monosaccharides as the correct answer based on their chemical structure and the given ratio.

Step 5: Conclude that monosaccharides are sugars with the 1:2:1 ratio of C:H:O, making them the correct answer to the problem.
