Answer:
Correct Answer: D
Solution:
In paroicous mosses (monoecious in nature) the two kinds of sex organs are borne in the same head in separate groups.
The antheridial and archegonial groups in the same head are demarcated from one another by one of two perichaetial bracts.
The monoecious mosses in which the two kinds of sex organs are borne on separate branches of the same plant are termed autoicous.
For example, Funaria hygrometrica.
