Answer

To determine which animal belongs to the class Crustacea, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification**: First, we need to recognize that Crustacea is a class within the phylum Arthropoda. This class includes various aquatic animals.

2. **Identify the Characteristics of Crustacea**: Crustaceans typically have a body divided into two main parts: the cephalothorax and the abdomen. They possess a hard exoskeleton known as a carapace, five pairs of appendages (totaling ten), compound eyes, two pairs of antennae, and they respire through gills or body surface.

3. **Examine the Options**: The options provided are:
- Mosquito
- Cyclops
- Prawn
- Grasshopper
- Cockroach

4. **Analyze Each Option**:
- **Mosquito**: This belongs to the class Insecta, characterized by three pairs of legs and wings. Therefore, it is not a Crustacean.
- **Cyclops**: This is a genus of small crustaceans, but it is often not the primary example of Crustacea. However, it is still part of this class.
- **Prawn**: This is a well-known example of a Crustacean, fitting all the characteristics mentioned earlier.
- **Grasshopper**: This also belongs to the class Insecta, with similar characteristics to mosquitoes.
- **Cockroach**: Like the grasshopper and mosquito, this belongs to the class Insecta.

5. **Determine the Correct Answer**: From the analysis, the only clear example of an animal that belongs to the class Crustacea is the **Prawn**.

### Final Answer:
The animal that belongs to the class Crustacea is **Prawn**.
