Answer:D

Explanation: Because it has the least amount of density in it. All the others are heavier, meaning they will sink. Just like if you drop a rock water and a feather, the feather will float.

Density def:

Density, mass of a unit volume of a material substance. ... Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).
