If an object has a density of less than [tex]1[/tex] g/ml, the object will float in water.
So, fourth option is correct
[tex]Density = \frac{Mass}{Volume}[/tex]
The object with density less than [tex]1[/tex] g/ml will float, and the object with a density more than [tex]1[/tex] g/ml will sink.
So, if an object has a density of less than [tex]1[/tex] g/ml, the object will float in water.
