Which of the following structures are characteristics of insect pollinated flowers?

The characteristics of insect-pollinated flowers are brightly colored petals, scent, and nectar. Insects are attracted to these features as they are searching for food, and as they feed on the nectar, they pick up pollen from the flower. The pollen is then transferred to other flowers, allowing for cross-pollination. In contrast, dull colored flowers with no nectar are usually wind-pollinated, as they do not need to attract insects for pollination. The stigma in insect-pollinated flowers is not feathery, but rather smooth and designed to collect pollen from the insects. Thus, the only option among the given choices that matches the characteristics of insect-pollinated flowers is "Brightly colored petals, scent, and nectar."
