The correct answer is B. Head.
A capitulum is a flower head that consists of many small flowers clustered together on a short stem. It is also known as a head or a capitulate inflorescence. The individual flowers in a capitulum are usually sessile, meaning that they are attached directly to the stem. The capitulum is often surrounded by a ring of bracts, which are modified leaves that protect the flowers.
The capitulum is a common type of inflorescence in the Asteraceae family, which includes sunflowers, daisies, and asters. It is also found in some other families of plants, such as the Compositae and the Cactaceae.
The capitulum is an adaptation that allows plants to produce a large number of flowers in a small space. This is beneficial for plants that rely on pollination by insects, as it increases the chances that the flowers will be pollinated.
The capitulum is also an adaptation that allows plants to produce a large amount of seed. This is beneficial for plants that rely on seed dispersal by wind, as it increases the chances that the seeds will be dispersed to new locations.
The capitulum is a beautiful and complex structure that plays an important role in the reproduction of many plants.
