I have the answer, I need the proper solution.

*16. Consider the following function with don't cares: G(X, Y, Z) = Em(5, 6) + Ed(1, 2, 4) For each of the following expressions, indicate whether it could be used as a solution for G. (Note: It may not be a minimum solution.) a. XYZ' + XY'Z d. Y'Z + XZ' + X'Z b. Z + XY'Z e. XZ' + X'Z c. X(Y' + Z') f. YZ' + Y'Z
