All of the following are isotropic materials except.
A
gases
B
liquids
C
monoclinic
D
amorphous material
E
minerals in cubic system
Explanation: 

Detailed explanation-1: -Isotropic materials are materials whose properties remain the same when tested in different directions. Isotropic materials differ from anisotropic materials, which display varying properties when tested in different directions. Common isotropic materials include glass, plastics, and metals.

Detailed explanation-2: -More solids belong to the monoclinic system than to any other. Beta-sulfur, gypsum, borax, orthoclase, kaolin, muscovite, clinoamphibole, clinopyroxene, jadeite, azurite, and spodumene crystallize in the monoclinic system.

Detailed explanation-3: -If a linearly elastic solid has one plane of material symmetry, it is called a monoclinic material.

Detailed explanation-4: -It is the opposite of isotropic. Wood and composite materials are good examples of anisotropic materials. Properties of these materials are dependent on directions; it means they show different properties in different directions. This type of behavior of these materials is called anisotropy.
