D Correct answer
Explanation

Plant classification is based on three key criteria: presence/absence of vascular tissue (distinguishes bryophytes from vascular plants), presence/absence of seeds (distinguishes seedless vascular plants from seed plants), and presence/absence of seed covering (distinguishes gymnosperms from angiosperms). Cell walls are present in ALL plant cells, so they cannot be used as a classification criterion.
