Solution

The correct option is A Wind
In Asteraceae, the calyx is not green and leafy as in other flowering plants, but is represented by a pappus at the base of each floret. The pappus consists of hairs, bristles or scales on the fruit. The pappus is an adaptation for wind dispersal of the fruit.
So, the correct answer is 'wind'
