A fir tree has leaves that stay green all year long. These trees produce cones, and their reproductive structures can be dispersed by the wind. To which group does the fir tree belong? nonvascular plants angiosperms gymnosperms seedless plants

gymnosperms

Explanation:

Gymnosperms are a diverse group of plant, second to angiosperms, that both belong to the HIGHER PLANTS category. Gymnosperms are characterized by their ability to bear seeds on naked structures called CONES. They do not produce flowers or fruits as opposed to gymnosperms.

They are usually evergreen i.e. do not shed their leaves all season long. According to this question describing a fir tree, which has leaves that stay green all year long and produce cones, that allows for wind dispersal, the fir tree is a GYMNOSPERM.
