Winged seeds are found in

Solution
The correct option is B Pinus
In Pinus some of the surface tissue of the ovuliferous scale remains attached to the seed, forming a membranous wing. These ovuliferous scales separate and the winged seeds fall from the cone. Wind movements disseminate the seeds a considerable distance from the parent plant. The embryo, enclosed within the dessication resistant seed coat, can remain dormant through extended periods of unfavorable environmental conditions. With seed germination, the embryo begins development into the new sporophyte generation.
