The best summary of the life cycle of a sponge is: "Sponges reproduce sexually, producing free-living larvae, which attach on a surface and metamorphose into adults."

Here's why:

1. Sponges are capable of both sexual and asexual reproduction. In asexual reproduction, a fragment of the sponge breaks off and grows into a new individual. However, this is not the only way sponges reproduce.

2. In sexual reproduction, sponges produce eggs and sperm. The sperm is often released into the water and taken in by other sponges, where it fertilizes the eggs.

3. The fertilized eggs develop into larvae, which are free-living and can move with the currents.

4. Eventually, the larvae settle onto a surface, attach to it, and metamorphose into adult sponges.

So, the third option is the most comprehensive and accurate summary of a sponge's life cycle.
