Answer

To determine the correct combination of mammals from the given options, we will analyze each option step by step.

### Step 1: Analyze the First Option - Seal, Dolphin, and Shark
- **Seal**: This is a mammal.
- **Dolphin**: This is also a mammal.
- **Shark**: This is not a mammal; it is classified as a cartilaginous fish.

**Conclusion**: Since one of the three (shark) is not a mammal, this combination is incorrect.

### Step 2: Analyze the Second Option - Dolphin, Seal, and Trigon
- **Dolphin**: This is a mammal.
- **Seal**: This is also a mammal.
- **Trigon**: This is a type of cartilaginous fish (related to stingrays).

**Conclusion**: Since Trigon is not a mammal, this combination is also incorrect.

### Step 3: Analyze the Third Option - Whale, Dolphin, and Seal
- **Whale**: This is a mammal.
- **Dolphin**: This is a mammal.
- **Seal**: This is a mammal.

**Conclusion**: All three are mammals. Therefore, this combination is correct.

### Step 4: Analyze the Fourth Option (if applicable)
- Since the question only provides three options, we do not need to analyze a fourth option.

### Final Conclusion
The correct combination of mammals is **Whale, Dolphin, and Seal**.
