If an object has a density of less than
g/ml, the object will float in water.
So, fourth option is correct

The object with density less than
g/ml will float, and the object with a density more than
g/ml will sink.
So, if an object has a density of less than
g/ml, the object will float in water.
Therefore, fourth option is correct
