Options

A. Rotenone
B. Nicotine
C. Azadirachtin
D. Devine

Answer

To solve the question of selecting the odd one with respect to insecticides from the given options (rotenone, nicotine, azadirachtin, and divine), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Rotenone
- Nicotine
- Azadirachtin
- Divine

2. **Analyze Each Option**:
- **Rotenone**: This is a naturally occurring compound that is used as an insecticide and pesticide. It is derived from the roots of certain plants and is known for its effectiveness against a variety of insects.
- **Nicotine**: This is an alkaloid found in tobacco plants. It is also used as an insecticide due to its toxic effects on insects, making it a common choice in pest control.
- **Azadirachtin**: This is a compound derived from the neem tree. It is widely recognized for its insecticidal properties and is used in organic farming as a natural pesticide.
- **Divine**: This is a trade name for a bioherbicide, which is specifically designed to control weeds rather than insects. It is not used as an insecticide.

3. **Determine the Odd One Out**:
- The first three options (rotenone, nicotine, and azadirachtin) are all insecticides. They are used to control insect populations.
- Divine, on the other hand, is a bioherbicide, which means it is used to control weeds and not insects.

4. **Conclusion**: Since Divine is the only option that does not function as an insecticide, it is the odd one out.

### Final Answer:
The odd one with respect to insecticide is **Divine** (option 4).
