The correct option is D Bryopsida
More than 95% of moss species belong to the Bryopsida. The most important characteristic of the Bryopsida is the architecture of the ring of teeth (peristome) surrounding the mouth of the sporophyte capsule. Bryopsida are the only mosses, that have an arthrodontous peristome, i.e., a peristome in which the teeth are structured by articulated cell wall remnants.
