Correct option (b) bryophytes and pteridophytes

Explanation:

Archegonium is the flask-shaped female reproductive body of bryophytes and pteridophytes. Archegonium usually consists of a tubular neck and a swollen venter. Neck is made up of 4-6 vertical row cf cells and encloses 6-10 neck canal cells in bryophytes and 4 vertical rows in pteridophytes enclosing 1-4 neck canal cells. Venter has 1-2 layer but it is wall-less in pteridophytes.
