To determine which group exhibits tissue level body organization, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Body Organization Levels**:
- There are different levels of body organization in animals: cellular, tissue, organ, and organ system levels.

2. **Identify the Options**:
- The options given are:
- A) Protozoa
- B) Porphyra
- C) Coelenterates
- D) Helminths

3. **Analyze Each Option**:
- **Protozoa**: These are unicellular organisms and exhibit cellular level organization.
- **Porphyra**: This is a type of red algae and does not exhibit tissue level organization as it is not an animal.
- **Coelenterates**: These organisms, such as jellyfish and corals, exhibit tissue level organization where specialized tissues perform specific functions.
- **Helminths**: These are flatworms and exhibit organ level organization.

4. **Conclusion**:
- Based on the analysis, the only group that exhibits tissue level body organization is **Coelenterates**.

### Final Answer:
