Solution

The correct option is B If both the assertion and reason are true but the reason is not a correct explanation of the assertion
In Dryopteris, young rhizome and leaves are covered with dry, brown, chaff y scales known as ramenta. In Pteridium, the rhizome and the leaves especially while young, are covered by a felt of simple hairs, and the scales are conspicuously absent.
