(A) is the right answer.
The *** organs in bryophytes are multicellular. The male *** organ is called antheridium. They produce biflagellate antherozoids. The female *** organ called archegonium is flask-shaped and produces a single egg. The antherozoids are released into water where they come in contact with archegonium. An antherozoid fuses with the egg to produce the zygote. Zygotes do not undergo reduction division immediately. They produce a multicellular body called a sporophyte.
