Answer:
Option B
Step-by-step explanation:
We are given the following system of equations -

Now by Cramer's Rule, we would first write down the matrix of the coefficients , replacing each column with the answer column -
,

Replace each column of the coefficients shown at the top, with the answer column at the bottom respectively -

Now solve through Cramer's Rule -
x = Dx / D = - 6,
y = Dy / D = - 1,
z = Dz / D = 1
<u><em>Solution = ( - 6, - 1, 1 ) = Option B</em></u>
