The correct option is D Liverworts and moss
Bryophyta are small, nonvascular plants, that first evolved approximately 500 million years ago. The earliest land plants were most likely Bryophytes. Bryophytes lack vascular tissue and have life cycles dominated by the gametophyte phase. The lack of conducting cells limit the size of the plants, generally keeping them under 5 inches high. Roots are absent in Bryophytes, instead there are root like structures known as rhizoids. Bryophytes include the hornworts, liverworts and mosses. Hence the correct option is D.
