In the given figure, the equation of the larger circle is \( x^{2}+y^{2}+4 y-5=0 \) and the distance between the centres of two circle is 4 . Write the equation for smaller circle.
a. \( (x+\sqrt{7})^{2}+(y-1)^{2}=1 \)
b. \( (x-\sqrt{7})^{2}+(y-1)^{2}=1 \)
c. \( x^{2}+y^{2}=3 \sqrt{7} x+3 y \)
d. None of these
