Answer:
Correct Answer: A
Solution:
Each sperm of Riccia is a minute, slender curved structure.
It is furnished with a pair of whiplash flagella at its anterior end.
The sperms do not leave the antheridium until enough moisture is present to permit them to swim about.
Several of the sperms may swim downward in the liquid in the neck.
