Answer:
A. No nonvascular plants bear seeds, but not all vascular plants bear seeds
Step-by-step explanation:
Nonvascular plants are those that do not have conductive vessels (xylem and phloem), in addition, nonvascular plants do not have seeds, fruits or flowers.
Some examples of nonvascular plants are mosses and liverworts.
Most vascular plants (have conductive vessels) have seeds, as in the case of angiosperms and gymnosperms, however, there are also some species of seedless vascular plants, represented by the lycopods and especially the pteridophytes, which are in greater number.
Examples of seedless vascular plants: ferns and horsetails.
