Consider the plane passing through the points $\mathrm{A}(2,2,1), \mathrm{B}(3,4,2)$ and $\mathrm{C}(7,0,6)$. What are the direction ratios of the normal to the plane?

• A

  $\langle 1,0,1\rangle$
• B

  $\langle 0,1,0\rangle$
• Correct answer
  C

  $\langle 1,0,-1\rangle$
• D

  None of these

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