Hornwort Sporophytes Have a Basal Region of Cell Division Rather

Hornwort sporophytes have a basal region of cell division rather than an apical region.What effect does this have on sporophyte function in hornworts, as compared with mosses?

A) It provides a place for symbiotic nitrogen-fixing bacteria to live, while in mosses the apical cell division creates structures for mycorrhizal fungi.
B) It allows spores to be continually made and released as long as the sporophyte lives, while in mosses only one set of spores is made per sporophyte.
C) It limits division of sporophytes to the base so hornworts do not get as tall as mosses.
D) It keeps making green tissue to support growth of the gametophyte, while in mosses the gametophyte supports the sporophyte.
E) It helps raise the spores so they can be more easily dispersed by symbiotic fungi, while in mosses the spores are dispersed by wind.
