Solution
The correct option is C Bryophytes and pteridophytes
An archegonium is the female reproductive organ in ferns, mosses, and gymnosperms. It is a flask-shaped structure, with a narrow neck, and a swollen base—the venter, which contains the egg (female gamete) hence serves as the site of fertilization. The neck is composed of 4 - 6 tiers of cells in bryophytes as wells as pteridophytes, inside it neck canal cells are found while in gymnosperms neck canal cells are absent.
So the correct answer is option B.
