A Correct answer
Explanation

S. officinalis is a hermaphrodite; each one has both ova and sperm. When ripe, their sperm escape the body through vents and float around the sea until they are sucked into the pores of another sponge by a water current. This sponge is dark grey or purplish when alive. When dry they can either be yellow or brown.
