If $2 \mathrm{x}-3 \mathrm{y}+1=0$ is the equation of the polar of a point $\mathrm{P}\left(\mathrm{x}_1, \mathrm{y}_1\right)$ with respect to the circle $x^2+y^2-2 x+4 y+3=0$, then $3 x_1-y_1=$

• A

  $\frac{1}{3}$
• B

  $-3$
• Correct answer
  C

  $3$
• D

  $-\frac{1}{3}$

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