Solution
The correct option is D Involucre
Capitulum or head bears many sessile and small florets. Main axis becomes flat and called receptacle. Peripheral florets called ray florets are pistillate or neuter and zygomorphic, whereas disc florets are bisexual and actinomorphic. At the base of flowers, a cluster of bracts forms an involucre (a whorl or rosette of bracts surrounding an inflorescence (especially a capitulum) or at the base of an umbel). Example: sunflower.
So, the correct answer is 'Involucre'.
