The Correct Option is D

Solution and Explanation

Step 1: Understanding elastic constants. - For an isotropic material, there are 2 independent elastic constants. - For an orthotropic material, there are 9 independent elastic constants. - For a non-homogeneous, non-isotropic material, there are 21 independent constants. Step 2: Selecting the correct option. Since a non-homogeneous, non-isotropic material requires 21 elastic constants, the correct answer is (D).
