Many sponges can reproduce asexually. Ladybugs, on the other hand, reproduce sexually.
When small bits of a sponge are broken off—often by currents or by predators—they can float to new regions and regenerate as new sponges. A ladybug must find a mate before it can reproduce.

One disadvantage of the sponge's method of reproduction is that
A.
its offspring have little genetic diversity.

B.
it requires more energy.

C.
it must devote a greater portion of its life cycle to reproduction.

D.
its offspring have greater genetic diversity.
