D
None of the above
Explanation: 

Detailed explanation-1: -Maple seeds have wing like outgrowth and are lightweight. Hence, they are dispersed by wind.

Detailed explanation-2: -Maple trees (genus Acer) accomplish the task of distributing objects to a wide area by producing seeds, known as samaras, which are carried by the wind as they autorotate and slowly descend to the ground.

Detailed explanation-3: -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-4: -More commonly referred to as “helicopters, ” “whirlers, ” “twisters” or “whirligigs, ” samaras are the winged seeds produced by maple trees. All maples produce samaras, but red, silver and Norway maples often produce the largest quantities.

Detailed explanation-5: -“Gliders” are seeds that have two wings, like the wings of an airplane. Jacaranda, for instance, produces plenty of flat, winged seeds that flutter away from the parent plant.
