Answer:
Correct Answer: B
Solution:
With the maturing of the sorus the indusium dries and shrivels, thus exposing the sporangia to dry air.
The sporangium consists of a stalk and a capsule.
The capsule consists of the annulus or organ of dehiscence and the stomium, which permits an easy cleavage when the mature sporangium begins to dehisce.
