Solution
The correct option is D Anthoceros
Class Anthocerotae belong to Bryophyta. They have dorsiventral, thallus plant body with unicellular rhizoids. The sporophyte is cylindrical like a horn with great amount of green tissues, and is partially dependent upon the gametophyte. The Archegonia in Anthoceros are present and are sunken in the thallus. There are no jacket cells covering the archegonium. The vegetative cells of the thallus provide protection to the archegonium. Cover cells or lid cells are found at the tip of the archegonia. Hence the correct option is D.
