Whether an object will float or sink in a liquid, depends on

  1. mass of the object only
  2. mass of the object and density of liquid only
  3. difference in the densities of the object and liquid
  4. mass and shape of the object only

Answer

Whether an object sinks or floats depends on the density of the object and the liquid in which it is immersed. An object that is denser than a liquid will sink in the liquid while an object that is less dense will float.  

The correct option is C.
