Solution
The correct option is C Archegonium
The sporophyte of Funaria starts developing within the archaegonia. The sex organs, antheridia and archegonia develop at the apices of seprate erect branches, called as gametophores. In the archaegonium the sporophyte is formed. A mature archegonium is flask shaped, which is borne on short stalk. It has a basal swollen part of venter and elongated neck. The venter is surrounded by a two layered jacket, whereas the jacket around the neck is singled layered. During heavy rains, the antherozoids reach the vicinity of archegonial neck and swim down to venter. Any one antherozoid fuses with egg to form zygote (2n). Soon, the zygote secretes a cell wall and becomes the oospore. The oospore divides and redivides to form embryo. Later the embryo grows into a sporophyte or sporogonium.
So, the correct answer is 'Archegonium'
