The correct answer is option 3: ferromagnetic property. Liquids and gases do not show ferromagnetic properties.

To understand why liquids and gases do not exhibit ferromagnetism, let`s first define what ferromagnetism is. Ferromagnetism is a property of certain materials that causes them to become permanently magnetized even in the absence of an external magnetic field. These materials are composed of atoms with unpaired electrons, which align their magnetic moments in the same direction.

In contrast, liquids and gases have randomly oriented magnetic moments due to their atomic and molecular structure. They do not have a well-defined magnetic domain structure like ferromagnetic materials. The individual magnetic moments in liquids and gases are constantly changing their orientation due to thermal motion, resulting in a lack of overall magnetization.

Therefore, liquids and gases cannot exhibit ferromagnetic properties. It is important to note that this property is specific to ferromagnetic materials and does not apply to liquids and gases.
