$\pi$ is a plane passing through the origin and containing two lines whose direction ratios are $1,-2,2$ and 2, 3, -1 then direction ratios of the line of intersection of the planes $x-y-z+1=0$ and $\pi$ are

• A

  $2,1,1$
• Correct answer
  B

  $2,3,-1$
• C

  $1,-2,2$
• D

  $-1,-1,0$

Hence, the correct answer is option: 'B'.
