Concept:Dry fruits with a feathery pappus or hair-like outgrowth are usually carried by air currents, so wind is the likely dispersal agent.
Explanation:The fruit in the diagram bears a pappus, which is a feathery or bristle-like structure.
This pappus increases the surface area of the fruit without adding much weight.
Because the fruit is light and has a large surface area, it can be lifted easily by wind.
Moving air carries the fruit away from the parent plant to new locations.
Although the bristles may sometimes cling to animal fur or clothing, the main agent of dispersal is wind.
Thus, the fruit is well adapted for wind dispersal.
Answer:D. wind
