Answer:
Correct Answer: D
Solution:
The leaves surrounding the antheridial cluster are known as the perigonial leaves.
They are closely set and spread out in the form of a rosette to form a shallow cup-like structure which affords protection to the antheridia and also acts as a splash cup.
Associated with the antheridia in the cluster are numerous, green, sterile, hair-like filaments.
They are multicellular and upright with large capitate heads and are called the paraphysis.
Each paraphysis is usually 4 to 6 cells in height.
