Correct Answer: B
Solution :
Morphologically Funaria looks dioecious, but it is monoecious. The antheridia (male sex organ) are formed at the summit of a relatively small, main leafy shoot which develops first. It is in fact the parent plant. The female branch arises later as a lateral outgrowth from the base of the parent male shoot. When the two kinds of the sex organs are borne in separate clusters on two distinct branches of the same plant the arrangement is called monoecious. Funaria is protandrous (male matures first). This ensures cross fertilization.
