Answer:

The right answer is D) Pinus.

Explanation:

  • Antheridia and archegonia are most reduced in Pinus.
  • Archegonia functions as a site of fusion (ie, fertilization) of male and female gametes  in lower plants.
  • An organ which produces and releases male gametes is called as Anteridium.
  • Male sex organs are called Antheridia.
  • Antheridia has a club-shaped body and stem and produces sperm or male gametes.
  • The sex organs of female are called archegonia.
  • Archegonia is a flask-shaped female sex organ with well-defined vents and neck.
  • The center surrounds the ventral canal cells (VCC) and the egg, and the neck surrounds a variable number of cervical cells (NCC).
  • Archegonia and Antheridia do not exist in angiosperms.
