A) Saline water is denser than pure water
B) Saline water is lighter than pure water
C) The viscosity of saline water is higher than that of pure water
D) None of these

The salt water's density becomes greater to the point that it is more-dense than the egg. Because the egg is now LESS dense than the water, it floats.
