Step 1: Concept
Entomophily is a form of pollination where pollen is distributed by insects, such as bees or butterflies.
Step 2: Meaning
Entomophilous flowers usually have adaptations like bright colors, nectar, or fragrance to attract pollinators.
Step 3: Analysis
Maize and Coconut are typically wind-pollinated (anemophily). Vallisneria is an aquatic plant that uses water for pollination (hydrophily). Salvia is famous for its specialized "lever mechanism" to deposit pollen on bees.
Step 4: Conclusion
Therefore, Salvia is the correct example of an insect-pollinated plant.
Final Answer: (C)
