Anisotropic means which one of the following a composite mat

Anisotropic means which one of the following: (a) composite materials with compositions consisting of more than two materials, (b) properties are the same in every direction, (c) properties vary depending on the direction in which they are measured, or (d) strength and other properties are a function of curing temperature?

Solution

anisotropic means having a physical property which has a different value vary in different directions

that is option c. and they are not function of temperature
