Provide an appropriate response.
-Suppose that you are solving a system of three linear equations and have evaluated $\mathrm { D } ^ { 2 } \mathrm { D } _ { \mathrm { X } } , \mathrm { D } _ { \mathrm { y } }$, and $\mathrm { D } _ { \mathrm { Z } }$. Under what condition does Cramer's rule not apply?
A) $\mathrm { D } _ { \mathrm { X } } = 0 , \mathrm { D } _ { \mathrm { y } } = 0$, or $\mathrm { D } _ { \mathrm { Z } } = 0$
B) $\mathrm { D } = 0$
C) $D _ { X } = 0$
D) $\mathrm { D } = 0$; and either $\mathrm { D } _ { \mathrm { X } } = 0 , \mathrm { D } _ { \mathrm { y } } = 0$, or $\mathrm { D } _ { \mathrm { z } } = 0$

Cramer's rule does not apply when the determinant of the coefficient matrix ($D$) is 0. If $D = 0$, the system does not have a unique solution.
