Answer 1

The correct option is B Head$/$ Capitulum

A. Umbel in which the main axis is reduced very much and all flowers appear to be arising from the same point. At the base of flowers, the cluster of bracts forming an involucre. It is a type of racemose inflorescence. The example is hydrocotyle.

B. Capitulum or head bears many sessile and small florets. The main axis becomes flat and called receptacle. It has a whorl of involucre bracts. It is a type of racemose inflorescence. The example is the sunflower.

C. Corymb in which the main axis is short and lower flowers have long pedicles than upper ones so that all the flowers are brought more or less to the same level. It is a type of cymose inflorescence. The example is iberis.

D. Raceme in which peduncle has bisexual and pedicellate flowers arranged acropetally. It is a type of racemose inflorescence. The example is a radish.

So, the correct answer is 'Head/Capitulum'.
