Options

A. Drosera and Rafflesia

C. Dionaea and Viscum
D. Rafflesia and Venus fly trap

Answer

To solve the question "A pair of insectivorous plants is?", we need to identify which of the given options consists of plants that feed on insects. Here's a step-by-step breakdown of the solution:

### Step 1: Understand the Definition of Insectivorous Plants
Insectivorous plants are those that derive some or most of their nutrients from trapping and consuming insects. This adaptation is usually found in nutrient-poor environments.

### Step 2: Analyze the Options Provided
We have four pairs of plants to consider:
1. **Drosera and Rafflesia**
2. **Nepenthes and Bladderwort**
3. **Dionaea and Viscum**
4. **Rafflesia and Venus Flytrap**

### Step 3: Evaluate Each Pair
- **Drosera and Rafflesia**:
- Drosera (Sundew) is an insectivorous plant, but Rafflesia is a root parasite, not insectivorous.

- **Nepenthes and Bladderwort**:
- Both Nepenthes (Pitcher plant) and Bladderwort are known insectivorous plants. This pair is a valid option.

- **Dionaea and Viscum**:
- Dionaea (Venus Flytrap) is insectivorous, but Viscum (Mistletoe) is a partial stem parasite, not insectivorous.

- **Rafflesia and Venus Flytrap**:
- Rafflesia is a root parasite, while Venus Flytrap is insectivorous. Thus, this pair is not valid.

### Step 4: Identify the Correct Pair
From the analysis, the only pair that consists of two insectivorous plants is **Nepenthes and Bladderwort**.

### Conclusion
The correct answer to the question "A pair of insectivorous plants is?" is **Nepenthes and Bladderwort**.
