PLZ HELP!!!! I ONLY HAVE 20MIN.

Gerald is fishing. He uses a bobber that floats on the surface to show him if the line is being moved, and a lure that sits below the surface to attract fish. Which statement accurately describes the densities of these two items?
1)The bobber and lure are more dense than the water.
2)The bobber and lure are less dense than the water.
3) The bobber is more dense than the water, and the lure is less dense than the water.
4)The bobber is less dense than the water, and the lure is more dense than the water.
