Answer 1

The correct option is A Poinsettia

An inflorescence is a group or cluster of flowers arranged on a stem that is composed of the main branch or a complicated arrangement of branches. In the genus Euphorbia, the flowers are in cup-shaped clusters called cyathia, each of which seems to be a single female flower but actually consists of a single pistil surrounded by several male flowers, each of which has a single stamen. The plant Poinsettia, have clusters of small, greenish, cup-shaped structures called cyathia. Each cyathium is actually a flower cluster or inflorescence containing unisexual, apetalous male and female flowers.

So the correct option is 'Poinsettia'.
