Carbohydrates are compounds of

Options

A. C,N,O
B. C, H,N
C. C,H,O
D. N, O, H

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Carbohydrates**: Carbohydrates are organic compounds that serve as one of the primary biomolecules in living organisms. They include sugars and starches.

2. **Composition of Carbohydrates**: Carbohydrates are composed of three essential elements: carbon (C), hydrogen (H), and oxygen (O).

3. **Ratio of Elements**: In carbohydrates, the ratio of hydrogen to oxygen is typically 2:1, which is similar to the ratio found in water (H₂O). This characteristic is a defining feature of carbohydrates.

4. **Examples of Carbohydrates**: Common examples of carbohydrates include glucose, fructose, and starch. Glucose is a simple sugar and is classified as a monosaccharide.

5. **Monosaccharides**: Monosaccharides are the simplest form of carbohydrates and cannot be hydrolyzed into simpler sugars. Glucose, for instance, has the molecular formula C₆H₁₂O₆.

6. **Conclusion**: Therefore, carbohydrates are compounds primarily made up of carbon, hydrogen, and oxygen, with specific structural characteristics that define their function in biological systems.
