Concept:The part labeled I is the petal, and petals form the corolla of a flower.
Their main role is to attract pollinators by being brightly coloured or scented.
Explanation:Petal is a sterile floral part, meaning it does not directly produce gametes.
It is usually the most conspicuous part of the flower because of its colour and shape.
Its bright appearance attracts insects, birds, or other pollinators to the flower.
Pollination is then made possible as the pollinators visit the flower for nectar.
The petal does not receive pollen grains; that is the function of the stigma.
It does not support pollen germination, which occurs on the stigma.
Double fertilization happens inside the embryo sac, not in the petal.
Thus, the labeled part I is correctly described by its role in attracting pollinators.
Answer:B. attract pollinators
