The correct option is A A- 3, B- 4, C- 1, D- 5, E- 2
In spike, the central axis is elongated but flowers are sessile, e.g., Achyranthes.
In capitulum, the receptacle is flat, bears sessile small florets in a centripetal manner, e.g., Zinnia.
In dichasial cyme, peduncle bears two bracts at a node from which two branches arise, e.g., Dianthus.
In multiparous cyme, peduncle bears single terminal flower and below it, more than two lateral branches arise from a node, e.g., Asclepia.
In verticillaster, there is a condensed dichasial cyme type inflorescence, e.g., Coleus.
Thus, the correct answer is option A.
