Volume. Squeeze a sponge--it gets smaller doesn't it? I can guess from this question you're a little confused regarding your concepts, so here goes:
1--mass does not change. Mass just refers to the amount of stuff there is. The number of atoms, say. So unless, you cut a part of the sponge off, it does not change in mass. Or maybe burned it--got rid of some of the atoms.
2--inertia does not change. Inertia is a quality related proportionally to mass.
3--weight does not change. Weight just refers to the force of gravity's pull on the object. It is a force. It is linked to mass as such:
Force = mass x acceleration.
So, I hope you understood that. Good luck with physics.

volume and inertia go down if im not mistaken, volume because you are putting more mass in less space, and inertia because it will spring back as soon as you stop compressing it

Volume if dry, volume and weight if you are supposed to consider if it has water in it. But I would say volume alone is the safest answer.

You make it smaller, right? Note that a wet sponge will also change some other things as well.

LOL.
Just the volume. Unless you discount all those little holes. Then NOTHING changes.
