Let $\mathrm{C}$ be the circle $x^{2}+y^{2}+4 x-6 y-3=0$ and $\mathrm{L}$ be the locus of the point of intersection of pair of tangents to $\mathrm{C}$ with the angle between the two tangents equal to $60^{\circ}$. Then, the point at which $\mathrm{L}$ touches the line $x=6$ is
- $(6,6)$
- $(6,8)$
- $(6,4)$
- $(6,3)$
