Write the basic solution for the simplex tableau determined by setting the nonbasic variables equal to 0.
2) x1 x2 x3 x4 x5 z
$\begin{bmatrix} 2 & 0 & 3 & 1 & 1 & 10 \ 1 & 1 & 2 & 4 & 0 & 7 \ 4 & 0 & 1 & 8 & 0 & 14 \end{bmatrix}$
A) x1 = 0, x2 = 7, x3 = 0, x4 = 0, x5 = 10, z = 14
B) x1 = 7, x2 = 0, x3 = 0, x4 = 10, x5 = 0, z = 14
C) x1 = 7, x2 = 0, x3 = 0, x4 = 0, x5 = 10, z = 14
D) x1 = 0, x2 = 7, x3 = 0, x4 = 10, x5 = 0, z = 14
