Verified step by step guidance

Step 1: Begin by recalling the basic chemical composition of carbohydrates and lipids. Both are organic molecules primarily composed of atoms that form the backbone of their structure.

Step 2: Understand that carbohydrates are made up of carbon (C), hydrogen (H), and oxygen (O) atoms. These elements are arranged in specific ratios, such as the general formula for monosaccharides: C₆H₁₂O₆.

Step 3: Similarly, lipids are composed of carbon (C), hydrogen (H), and oxygen (O) atoms. Lipids, such as triglycerides, consist of glycerol and fatty acids, which also contain these three types of atoms.

Step 4: Eliminate the incorrect options by identifying elements that are not common to both carbohydrates and lipids. For example, nitrogen (N), sulfur (S), and phosphorus (P) are not universally present in both carbohydrates and lipids.

Step 5: Conclude that the three types of atoms found in both carbohydrates and lipids are carbon (C), hydrogen (H), and oxygen (O), as these are the fundamental building blocks of these biomolecules.
