(A) In liverworts, mosses, and ferns, gametophytes are free-living
(B) Gymnosperms and some ferns are heterosporous.
(C) Sexual reproduction in Fucus, Volvox, and Albugo is oogamous.
(D) The sporophyte in liverworts is more elaborate than that in mosses.
(E) Both, Pinus and Marchantia are dioecious.

How many of the above statements are correct?

• A. Two
• B. Three
• C. Four
• D. One

Answer 1

The correct option is B Three

• Gametophytes of liverworts, mosses, and ferns are independent and so are free-living.
• Gymnosperms and some ferns are heterosporous, meaning has two different types of spores.
• Sexual reproduction in Fucus, Volvox, and Albugo is monogamous meaning they have small flagellated male gamete and large non-flagellated female gamete.
• The sporophyte of moss is more elaborate than the liverworts.
• Pinus is monoecious while Marchantia is dioecious.

Thus, the correct answer is option (C), 'Three'.
