D. Branch modified into pitcher.

Answer

To solve the question regarding the characteristics of non-insectivorous pitcher plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pitcher Plants**:
- Pitcher plants are generally known for their modified leaves that form a structure resembling a pitcher or jug. These plants are primarily carnivorous, meaning they trap and digest insects.

2. **Identifying Non-Insectivorous Pitcher Plants**:
- Non-insectivorous pitcher plants differ from their insectivorous counterparts. They do not rely on trapping insects for nutrition.

3. **Characteristics of Non-Insectivorous Pitcher Plants**:
- One key characteristic is the **absence of digestive fluids**. Unlike insectivorous pitcher plants, non-insectivorous types do not have the fluids that digest prey.
- Another important feature is the **absence of a lid**. In insectivorous pitcher plants, the lid closes to trap the insect inside, but in non-insectivorous pitcher plants, this lid is not present.

4. **Evaluating the Options**:
- The options provided were:
- A) Closed lid
- B) Foul smell
- C) Absence of lid
- D) Branch modified into pitcher
- Based on our understanding, the correct answer is **C) Absence of lid**, as non-insectivorous pitcher plants do not have a lid to trap insects.

5. **Conclusion**:
- Therefore, the characteristic that defines non-insectivorous pitcher plants is the **absence of a lid**.

### Final Answer:
**C) Absence of lid**
