Options

A. Ammonia is easily soluble in water
B. ammonia is released from the body is a gaseous state.
C. Ammonia is higly toxic and needs to be eliminated when formed.
D. both a and b

Answer

To solve the question regarding the excretion of ammonia by aquatic animals and identify which statement is not in agreement with this situation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**:
- Almost all aquatic animals excrete ammonia as their nitrogenous waste product. This is due to the high solubility of ammonia in water and the need for quick elimination due to its toxicity.

2. **Analyze the Statements**:
- We need to evaluate the statements provided in the question to identify which one does not align with the known facts about ammonia excretion.

3. **Statement Evaluation**:
- **Statement A**: "Ammonia is easily soluble in water."
- **Analysis**: Ammonia (NH3) is indeed soluble in water. This statement is true.

- **Statement B**: "Ammonia is released from the body in gaseous state."
- **Analysis**: Ammonia is typically excreted in solution (dissolved in water) and not as a gas. This statement is false.

- **Statement C**: "Ammonia is highly toxic and needs to be eliminated when formed."
- **Analysis**: This statement is true as ammonia is toxic and must be removed quickly from the body.

4. **Identify the Incorrect Statement**:
- From the analysis, Statement B is the one that is not in agreement with the situation because ammonia is not released in a gaseous state.

5. **Conclusion**:
- The statement that is not in agreement with the situation regarding ammonia excretion by aquatic animals is **Statement B**.

### Final Answer:
The statement that is not in agreement with the situation is: **"Ammonia is released from the body in gaseous state."**
