If two circles which pass through the points \( (0, a) \) and \( (0,-a) \) cut each other orthogonally and touch the straight line \( y=m x+c \), then
(a) \( c^{2}=a^{2}\left(1+m^{2}\right) \)
(b) \( c^{2}=a^{2}\left|1-m^{2}\right| \)
(c) \( c^{2}=a^{2}\left(2+m^{2}\right) \)
(d) \( c^{2}=2 a^{2}\left(1+m^{2}\right) \)
