One of the following is a polysaccharide

Options

A. Chitin
B. Glucose
C. Sucrose
D. Maltose

Answer

To determine which of the following options is a polysaccharide, we need to understand the classification of carbohydrates and identify examples of each category.

### Step-by-Step Solution:

1. **Understand Carbohydrate Classification**: Carbohydrates are classified into three main categories: monosaccharides, disaccharides, and polysaccharides.
- **Monosaccharides**: These are the simplest form of carbohydrates. Examples include glucose, fructose, and ribose.
- **Disaccharides**: These consist of two monosaccharide units. Examples include sucrose, maltose, and lactose.
- **Polysaccharides**: These are complex carbohydrates made up of many monosaccharide units. Examples include starch, glycogen, and chitin.

2. **Identify the Options**: The question asks for a polysaccharide. We need to evaluate the given options (though not explicitly listed here, we can infer based on the transcript) to see which one fits the definition of a polysaccharide.

3. **Evaluate Each Option**:
- If one of the options is **glucose**, it is a monosaccharide and therefore incorrect.
- If one of the options is **sucrose**, it is a disaccharide and therefore incorrect.
- If one of the options is **chitin**, it is a polysaccharide and therefore correct.

4. **Conclusion**: Among the options provided, **chitin** is the correct answer as it is a polysaccharide. Chitin is known to be the most abundant polysaccharide on Earth and is found in the exoskeletons of shrimp, crabs, and insects.

### Final Answer:
The polysaccharide among the options is **chitin**.
