Plants of which one of the following groups of genera are pollinated by same agency?

Options

A. Triticum, Mussanda, Zea mays
B. Kadamb, Cannabis
C. Salvia, Calotropis, Rafflesia
D. Salvia, Pinus, Ophrys

Explanation

To solve the question of which group of genera is pollinated by the same agency, we need to analyze the pollination methods of the plants listed in the options.

### Step-by-Step Solution:

1. **Identify the Genera and Their Pollination Agents:**
- **Triticum (Wheat)**: Pollinated by wind.
- **Zea (Maize)**: Pollinated by wind.
- **Musa (Banana)**: Pollinated by insects.

From the first option, we see that Triticum and Zea are both wind-pollinated, but Musa is not.

2. **Analyze the Second Option:**
- **Kadam Tree**: Pollinated by bats.
- **Cannabis**: Pollinated by wind.

In this case, Kadam tree and Cannabis are not pollinated by the same agency.

3. **Examine the Third Option:**
- **Salvia**: Pollinated by insects.
- **Calotropis**: Pollinated by insects.
- **Rafflesia**: Pollinated by carrion flies (a type of insect).

Here, all three plants are pollinated by insects, making this option consistent.

4. **Evaluate the Fourth Option:**
- **Salvia**: Pollinated by insects.
- **Ophrys**: Pollinated by a specific insect (Pavasp).
- **Pinus**: Pollinated by wind.

This option has a mix of pollination methods (insects and wind), so it does not fit.

5. **Conclusion:**
The only group of genera that are all pollinated by the same agency (insects) is the third option: Salvia, Calotropis, and Rafflesia.

### Final Answer:
The correct answer is **Option 3: Salvia, Calotropis, and Rafflesia**.
