Solution
The correct option is A Bracts The flowers of Bougainvillea are bright pink in colour because of the colour of the bracts. These flowers do not have a distinct and differentiated corolla as well as calyx. Three tiny flowers are surrounded by the bracts. These bracts are modified leaves. They protect the flower and attract the pollinators.
