Carbohydrate that on attempt hydrolysis are not cleaved to smaller carbohydrates are called :

Options

A. Monosaccharide
B. Oligosaccharide
C. Polysaccharide
D. Disaccharide

Explanation

**Step-by-Step Solution:**

1. **Understanding Carbohydrates**: Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen. They are classified into three main categories: monosaccharides, oligosaccharides, and polysaccharides.

2. **Definition of Monosaccharides**: Monosaccharides are the simplest form of carbohydrates. They cannot be hydrolyzed into smaller carbohydrates. Examples include glucose, fructose, and galactose.

3. **Oligosaccharides**: These are carbohydrates that consist of 2 to 10 monosaccharide units. They can be hydrolyzed into smaller carbohydrates. For example, sucrose (a disaccharide) can be hydrolyzed into glucose and fructose.

4. **Polysaccharides**: These are complex carbohydrates made up of many monosaccharide units (more than 10). They can also be hydrolyzed into monosaccharides. Examples include starch and glycogen.

5. **Conclusion**: Since the question asks for carbohydrates that cannot be cleaved into smaller carbohydrates upon hydrolysis, the answer is monosaccharides.

**Final Answer**: Monosaccharides are carbohydrates that on attempted hydrolysis are not cleaved to smaller carbohydrates.
