### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about plants that have pleasant odors and attractive colors. This is typically a characteristic feature of certain types of pollination.

2. **Identifying the Options**: The options provided are:
- Entomophilia (insect pollination)
- Hydrophilia (water pollination)
- Anemophilia (wind pollination)
- All of the above

3. **Analyzing Entomophilia**:
- Entomophilia refers to pollination that occurs through insects.
- Plants that utilize this method often have bright colors and emit pleasant scents to attract insects for pollination.

4. **Analyzing Hydrophilia**:
- Hydrophilia is the process of pollination by water.
- Typically, plants that rely on water for pollination do not have vibrant colors or strong scents, as they do not need to attract insects.

5. **Analyzing Anemophilia**:
- Anemophilia refers to wind pollination.
- Similar to hydrophilia, plants that depend on wind do not usually have attractive colors or odors, as they rely on the wind to carry their pollen.

6. **Conclusion**: Given the characteristics of each type of pollination, the only option that fits the description of plants having pleasant odors and attractive colors is **Entomophilia**. Therefore, the correct answer is **Entomophilia**.

### Final Answer:
The correct option is **Entomophilia**.
