C. Rafflesia in group I should be interchanged with Hibiscus in group III.
D. Utricularia in group II should be interchanged with Rafflesia in group I whereas Dionaea in group III should be replaced with Ocimum.

Explanation

To solve the problem of identifying the incorrect member in each group of plants classified by Radhika, we will analyze each group one by one.

### Step 1: Analyze Group I
- **Group I Members**: Nepenthes, Rafflesia, Drosera
- **Characteristics**:
- Nepenthes and Drosera are both insectivorous plants, meaning they eat insects.
- Rafflesia, on the other hand, is not insectivorous; it is a parasitic plant.

**Conclusion for Group I**: Rafflesia is the odd member out because it does not share the characteristic of being insectivorous with Nepenthes and Drosera.

### Step 2: Analyze Group II
- **Group II Members**: Cuscuta, Hydnora, Utricularia
- **Characteristics**:
- Cuscuta and Hydnora are both parasitic plants.
- Utricularia is an insectivorous plant.

**Conclusion for Group II**: Utricularia is the odd member out because it does not share the characteristic of being parasitic with Cuscuta and Hydnora.

### Step 3: Analyze Group III
- **Group III Members**: Hibiscus, Petunia, Dionaea
- **Characteristics**:
- Hibiscus and Petunia are known for their medicinal properties.
- Dionaea (commonly known as the Venus flytrap) is an insectivorous plant.

**Conclusion for Group III**: Dionaea is the odd member out because it does not share the characteristic of being a medicinal plant with Hibiscus and Petunia.

### Final Summary
- **Odd Members Identified**:
- Group I: Rafflesia
- Group II: Utricularia
- Group III: Dionaea
