Multiple Choice

Provide an appropriate response.
-Suppose that you are solving a system of three linear equations and have evaluated $D _ { , } D _ { X } , D _ { y }$ , and $D _ { Z }$ . Under what condition does Cramer's rule not apply?

A) $\mathrm { D } = 0$ ; and either $\mathrm { D } _ { \mathrm { X } } = 0 , \mathrm { D } _ { \mathrm { y } } = 0$ , or $\mathrm { D } _ { \mathrm { Z } } = 0$
B) $\mathrm { D } = 0$
C) $\mathrm { D } _ { \mathrm { X } } = 0$
D) $\mathrm { D } _ { \mathrm { X } } = 0 , \mathrm { D } _ { \mathrm { y } } = 0$ , or $\mathrm { D } _ { \mathrm { Z } } = 0$
