\( C_{1} \) is a circle of radius 1 touching the \( x \)-axis and the \( y \)-axis. \( C_{2} \) is another circle of radius \( 1 \) and touching the axes as well as the circle \( C_{1} \). Then the radius of \( C_{2} \) is
(a) \( 3-2 \sqrt{2} \)
(b) \( 3+2 \sqrt{2} \)
(c) \( 3+2 \sqrt{3} \)
(d) none of these
