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

Options

A. Triticum, Cocos, Mangifera
B. Ficus, Kigelia, Casuarina
C. Salvia, Morus, Euphorbia
D. Bombax, Butea, Bahinia

Explanation

To solve the question regarding which group of genera are pollinated by the same agency, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Pollination**:
- Pollination is the process where pollen grains from the male reproductive organ (anther) are transferred to the female reproductive organ (stigma) of a flower.
- This process is essential for fertilization in flowering plants (angiosperms).

2. **Identify Types of Pollination**:
- There are two main types of pollination:
- **Abiotic Pollination**: Involves non-living agents like wind and water.
- **Biotic Pollination**: Involves living agents, primarily animals such as insects, birds, and bats.

3. **Analyze the Given Genera**:
- The question provides several groups of genera. We need to determine which group is pollinated by the same agency.
- The options include:
- A) Ficus, Cygalea, and Casuarina
- B) (Other options not provided in the transcript)
- C) (Other options not provided in the transcript)
- D) (Other options not provided in the transcript)

4. **Research Pollination Mechanisms**:
- **Ficus**: Known to be pollinated by tiny wasps (a biotic agent).
- **Cygalea**: Pollinated by bats (another biotic agent).
- **Casuarina**: Also pollinated by biotic agents, specifically wind and insects.

5. **Conclusion**:
- Since Ficus and Cygalea are both pollinated by biotic agents (though different ones), and Casuarina is primarily wind-pollinated, we need to focus on the commonality.
- The correct answer is **Option B: Ficus, Cygalea, and Casuarina**, as they all involve biotic agents, albeit with some differences.

### Final Answer:
The plants of the group of genera that are pollinated by the same agency are **Ficus, Cygalea, and Casuarina**.
