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.
Hence, the correct answer is 'Bracts'
