The correct option is A Capitulum inflorescence
A head (capitulum) is a short dense spike in which the flowers are borne directly on a broad, flat peduncle, giving the inflorescence the appearance of a single flower, as in the Dandelion (Taraxacum).
Capitulum inflorescence is present only in Compositae.
In Solanaceae inflorescence is Cymose. Gamopetalous corolla, epipetalous stamens and bicarpellary gynoecium are common in both Solanaceae and Compositae.
Therefore, the correct answer is option A.
