I think it is the secondary ovarian follicle that contains the secondary oocyte.The stages of the ovarian cycle that the follicle will go through includes; a primary follicle contains an oocyte and begins producing estrogen. Then the secondary oocyte contains a secondary oocyte and produces estrogen and some progesterone, then the graafian follicle develops and the secondary oocyte is released a process we call ovulation. the corpus luteum produces progesterone and some estrogen and lastly the corpus luteum degenerates.

Answer:
The correct option is 'c'
The archaea and bacteria diverge from early eukarya.
Explanation:
The cell wall material is different from archaea with bacteria as the cell wall of archaea lack peptidoglycan and contain lipid and hydrocarbons rather than fatty acid but the cell wall of bacteria contain peptidoglycans.
Archaea and bacteria both derived from eukarya as they both have similarities with eukarya.
The similarity between archaea and bacteria is that they both share lateral gene transfer.
There are similar features that are seen between archaea and bacteria like protein secretion,ATP production,protein modification etc.
Both bacteria and eukarya belongs to prokaryotes and the membrane of both eukarya and bacteria contain unbranched fatty acid chain that are attached to glycerol with ester bond.
