Answer: Option (A) is the correct answer.
Explanation:
Plastic deformation is the change in shape of an object or metal caused by the load of excess stress.
Thus, metals experience plastic deformation when their crystal patterns have been disrupted by stress.
When stress is provided to the metal then their crystal pattern gets deformed resulting in change of shape of the metal. Plastic deformation is a permanent deformation.
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.
