The correct option is C Two or more
Archegonia in gymnosperm
The ovule or megasporangium in gymnosperms contains a mass of diploid cells called nucellus. One of the cells of the nucellus becomes a megaspore mother cell and undergoes meiosis to form four haploid megaspores.
One of the megaspore cells differentiates to form the female gametophyte which produces two or more haploid multicellular sex organs called archegonia.
