Solution
The correct option is D archegonium
The gametophytes (prothallus) of pteridophyte bear male and female sex organs called antheridia and archegonia, respectively. Water is required for the transfer of antherozoids – the male gametes released from the antheridia to the mouth of the archegonium for fusion of male gamete with the egg. The egg is present in the archegonium that results in the formation of a zygote after fertilization. Zygote thereafter produces a multicellular well-differentiated sporophyte which is the dominant phase of the pteridophytes. Hence, the correct answer is archegonium.
