If tangent at \( (1,2) \) to the circle \( c_{1}: x^{2}+y^{2}=5 \) intersects the circle \( c_{2}: x^{2}+y^{2}=9 \) at \( A \& B \) and tangents at \( A \& B \) to the second circle meet at point \( C \), then the co-ordinates of \( C \) is
\( \mathrm{P} \)
(A) \( (4,5) \)
(B) \( \left(\frac{9}{15}, \frac{18}{5}\right) \)
(C) \( (4,-5) \)
(D) \( \left(\frac{9}{5}, \frac{18}{5}\right) \)
