If the parametric values of two points \(A\) and \(B\) on the circles \(x^2+y^2-6 x+4 y-12=0\) are \(30^{\circ}\) and \(90^{\circ}\) respectively, then the equation of chord \(\mathbf{A B}\) is
- A \(x+\sqrt{3} y=0\)
- B \(x-\sqrt{3} y=0\)
- C \(x+\sqrt{3} y-3(1+\sqrt{3})=0\)
- D \(\sqrt{3} x+\sqrt{3} y+61=0\)
