Solution
The correct option is A Propeller
A tuft of hair present at one or both ends of the seed (for dispersal) is known as propellar. The wing typically has a slight pitch (like a propeller or fan blade), the one-winged propeller type, as found in maple, is called a samara. A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit and indehiscent. The shape of a samara enables the wind to carry the seed farther away than regular seeds from the parent tree. The seed can be in the centre of the wing or the seed can be on one side, with the wing extending to the other side, making the seed autorotate as it falls.
