The body temperature of an animal at `20^@` DC is same as its temperature at `30^@` DC. It can be included under the category

Options

A. conformers
B. regulators
C. poikilotherms
D. euryhaline

Answer

To solve the question regarding the body temperature of an animal at `20°C` being the same as its temperature at `30°C`, we can analyze the characteristics of different categories of organisms based on their ability to regulate body temperature.

### Step-by-Step Solution:

1. **Understanding the Question**: The question states that the body temperature of an animal is the same at two different environmental temperatures: `20°C` and `30°C`. This indicates that the animal's body temperature does not change with the surrounding temperature.

2. **Identifying Categories**: We need to categorize the animal based on its ability to maintain body temperature. The possible categories mentioned are:
- Confirmers
- Regulators
- Poikilotherms
- Urethaline

3. **Defining Confirmers**: Confirmers are organisms that cannot maintain a constant body temperature. Their body temperature varies with the environmental temperature. Examples include most insects, amphibians, and fishes.

4. **Defining Regulators**: Regulators are organisms that can maintain a constant body temperature regardless of environmental conditions. For instance, humans maintain a body temperature of around `37°C` even when external temperatures vary significantly.

5. **Defining Poikilotherms**: Poikilotherms are similar to confirmers; they cannot regulate their body temperature and their body temperature fluctuates with the environment.

6. **Defining Urethaline**: Urethaline organisms can thrive in a wide range of salinity, which is not directly related to body temperature regulation.

7. **Conclusion**: Since the animal in question maintains the same body temperature at both `20°C` and `30°C`, it indicates that it can regulate its body temperature. Therefore, it fits into the category of **Regulators**.

### Final Answer:
The animal can be included under the category of **Regulators**.
