Cho 2 đường thẳng

Câu hỏi: Cho 2 đường thẳng $d_1:\left\{\begin{array}{l}x=2+t\\ y=1-t\\ z=2-t\end{array}\right.$ và $d_2:\left\{\begin{array}{l}x=3+t^{\text{'}}\\ y=2+t^{\text{'}}\\ z=5\end{array}\right.$.Phương trình đường vuông góc chung $∆$ của $d_1,d_2$là

A. $\Delta :\left\{\begin{array}{l}x=1+t^{\text{'}\text{'}}\\ y=2-t^{\text{'}\text{'}}\\ z=3+2t^{\text{'}\text{'}}\end{array}\right.$

B. $\Delta :\left\{\begin{array}{l}x=1-t^{\text{'}\text{'}}\\ y=2-t^{\text{'}\text{'}}\\ z=3+2t^{\text{'}\text{'}}\end{array}\right.$

C. $\Delta :\left\{\begin{array}{l}x=-1+t^{\text{'}\text{'}}\\ y=2-t^{\text{'}\text{'}}\\ z=3+2t^{\text{'}\text{'}}\end{array}\right.$

D. $\Delta :\left\{\begin{array}{l}x=1+t^{\text{'}\text{'}}\\ y=-2-t^{\text{'}\text{'}}\\ z=-3+2t^{\text{'}\text{'}}\end{array}\right.$
