State the characters ideal for dispersion by wind.
A
Small, light and hair-like
B
Small, light and sharp hooks
C
Big, light and fibrous husk
D
Big, light and explode
Explanation: 

Detailed explanation-1: -Seeds of some plants are light-weight and some hair-like or wing-like structures are present on them. Such seeds float on air and are thus dispersed by wind. Example: Dandelion, maple, drumstick, etc.

Detailed explanation-2: -Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds. They don’t float away but flutter to the ground.

Detailed explanation-3: -Seeds are light and readily carried by the wind. The seeds of trees and other plants are often dispersed over long distances. Some seeds, such as those of dandelions, have wings that enable them to be carried long distances by the wind. Water dispersal is another common method of seed dispersal.

Detailed explanation-4: -Hairy structures, light weight, small size etc. help the seeds to disperse by the help of wind.

Detailed explanation-5: -Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. Some have a parachute-like structure to keep them afloat. Some fruits, such as the dandelion, have hairy, weightless structures that are suited to dispersal by wind.
