If the angle between the pair of lines $2 x^2+2 h x y+2 y^2-x+y-1=0$ is $\operatorname{Tan}^{-1}(3 / 4)$ and $h$ is a positive rational number, then the point of intersection of these two lines is

• A

  $(1,-1)$
• B

  $\left(\frac{-1}{9}, \frac{1}{9}\right)$
• Correct answer
  C

  $(-1,1)$
• D

  $(3,2)$

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