Solution
The correct option is B Involucre
Capitulum or head bears many sessile and small florets. The main axis becomes flat and called receptacle. At the base of flowers, a cluster of bracts forms an involucre. Peripheral florets called ray florets are pistillate or neuter and zygomorphic, whereas disc florets are bisexual and actinomorphic is called heterogamous. It is a type of racemose inflorescence. Example: sunflower.
