Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { l l }
x - y & + 4 z = 3 \
3 x & + z = 0 \
x + 5 y & + z = - 15
\end{array}$$
A) Cramer's rule does not apply since $\mathrm { D } = 0$; $\varnothing$
B) $\{ ( 0,0 , - 3 ) \}$
C) $\{ ( 0 , - 3,3 ) \}$
D) $\{ ( 0 , - 3,0 ) \}$
