If an object is neutrally buoyant (does not sink or float) in fresh water, the same object placed into salt water wouldA sink. B either sink or float. C do nothing. D float.

D float.

Explanation:

Here, neutrally buoyant in fresh water

Now,

since the specific gravity of salt water is higher than the specific gravity of the fresh water therefore, the salt water will apply more buoyant force on the object.

And as the object is neutral in fresh water, more buoyant force will make the object float in the salt water.
