The difference between the radii of the largest and
\( \mathrm{P} \) the smallest circles which have their center on the

W circumference of the circle \( x^{2}+y^{2}+2 x+4 y-4=0 \) and pass through the point \( (a, b) \) lying outside the given circle is
(1) 6
(2) \( \sqrt{(a+1)^{2}+(b+2)^{2}} \)
(3) 3
(4) \( \sqrt{(a+1)^{2}+(b+2)^{2}}-3 \)
