Trong không gian Oxyz, cho ba điểm \(A\left( {1; - 1;1} \right),B\left( { - 1;0;2} \right),C\left( {2;1;3} \right)\).

A. \(\left\{ \begin{array}{l}
x = 1 + 3t\\
y =  - 1 - t\\
z = 1 + t
\end{array} \right..\)

B. \(\left\{ \begin{array}{l}
x = 1 + 3t\\
y =  - 1 + t\\
z = 1 + t
\end{array} \right..\)

C. \(\frac{{x - 1}}{{ - 3}} = \frac{{y + 1}}{1} = \frac{{z - 1}}{{ - 1}}.\)

D. \(\left\{ \begin{array}{l}
x = 1 + 3t\\
y =  - 1 - t\\
z = 1 - t
\end{array} \right..\)
