Answer : 4. "Insect"
Explanation :
Fragrant flowers attract pollinators like bees, butterflies, and birds with their pleasant scent. These pollinators visit the flowers to feed on nectar or collect pollen. During their visits, they unintentionally transfer pollen from one flower to another, facilitating pollination. This process enables the plant to reproduce and produce seeds. Different plants rely on specific pollinators, ensuring their reproductive success and genetic diversity within the ecosystem.
