Answer:
Answer is Object 2 (which has a density of 1.9 g/cm³).
Explanation;
When object is floating, the weight of that object is less than the up thrust on it.
When an object fully submerged and floating, then the weight of that object is equal to the up thrust on it.
This is known as the Archemide's principle.
Both up thrust and weight depends on the density. Hence, if the density of the solution is high, then the up thrust also high. If the density high, the the weight of the object also high.
Hence, to sink the object in water, that object should be denser than water. Hence, answer is object 3 which has a higher density than water.

hope i helped
pls mark brainliest,,,,,thanks
Colligative properties are those substances that depend
on the number of substances in the solution, not in the identity of that
substance. The property changes the way that it does when the amount of solute
is increased because it enables the solute to be scattered more. For example,
the freezing point of salt water is lower than that of the pure water due to
the salt ions present in water.
