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

Options

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

Explanation

To determine which group of genera is pollinated by the same agency, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Examine the First Option: Triticum, Cocos, Mangifera**
- **Triticum (Wheat)**: Pollinated by wind.
- **Cocos (Coconut)**: Pollinated by honey bees or wasps.
- **Mangifera (Mango)**: Typically pollinated by insects, especially flies and bees.
- **Conclusion**: Since Triticum is wind-pollinated while Cocos and Mangifera are insect-pollinated, this option is incorrect.

2. **Examine the Second Option: Ficus, Cygelia**
- **Ficus**: Pollinated by wasps.
- **Cygelia**: Pollinated by bats or wind.
- **Conclusion**: Since Ficus is wasp-pollinated and Cygelia is not consistently pollinated by the same agency (bats or wind), this option is also incorrect.

3. **Examine the Third Option: Salvia, Morus**
- **Salvia**: Pollinated by birds.
- **Morus (Mulberry)**: Pollinated by insects.
- **Conclusion**: Since Salvia is bird-pollinated and Morus is insect-pollinated, this option is incorrect as well.

4. **Examine the Fourth Option: Bombax, Butea, Bohemia**
- **Bombax**: Pollinated by birds.
- **Butea**: Pollinated by birds.
- **Bohemia**: Pollinated by birds.
- **Conclusion**: All three genera are pollinated by birds. This indicates that they share the same pollinating agency.

5. **Final Conclusion**: The correct answer is the fourth option: **Bombax, Butea, and Bohemia**, as they are all pollinated by birds, which is a type of pollination known as **Ornithophilia**.
