Answer 1

The correct option is C Cyathium

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, a cluster of bracts forms an involucre. It is a type of racemose inflorescence. An example is hydrocotyle.

B. A corymb is lower flowers have long pedicels than upper ones so that all the flowers are brought more or less to the same level. The main axis is short. It is a type of racemose inflorescence. Examples are Iberis and Capsella.

C. Cyathium looks like a single flower. A cup-shaped involucre formed by bracts encloses a single female flower and a number of male flowers. Each male flower is represented by a single stamen while a single pistil represents a female flower. It is a type of cymose inflorescence. Examples are Poinsettia and Pedilanthus.

D. Capitulum or head bears many sessile and small florets. The main axis becomes flat and called receptacle. It is a type of racemose inflorescence. An example is sunflower.

So, the correct answer is 'Cyathium'.
