Entomophily takes place by:

Insect

The correct answer is Option (1) → Insect

Entomophily takes place by "insects." Entomophily, also known as insect pollination, is a method of pollination where pollen is transferred from the male reproductive organs to the female reproductive organs of a flower by insects. Insects such as bees, butterflies, moths, beetles, and flies are common pollinators that visit flowers in search of nectar or pollen. As they move from flower to flower, they inadvertently pick up and deposit pollen, facilitating the pollination process. Many flowering plants have evolved specific adaptations to attract and accommodate insect pollinators, including brightly colored flowers, nectar guides, and sweet fragrances.
