Consider the circles
\[
\begin{array}{l}
C_{1} \equiv x^{2}+y^{2}-2 x-4 y-4=0 \text { and } \\
C_{2} \equiv x^{2}+y^{2}+2 x+4 y+4=0
\end{array}
\]
\( \mathrm{P} \)
W
and the line \( L \equiv x+2 y+2=0 \), then
(a) \( L \) is the radical axis of \( C_{1} \) and \( C_{2} \)
(b) \( L \) is the common tangent of \( C_{1} \) and \( C_{2} \)
(c) \( L \) is the common chord of \( C_{1} \) and \( C_{2} \)
(d) \( L \) is perpendicular to the line joining centres of \( C_{1} \) and \( C_{2} \)
