C_1

and

C_2

and radii

r_1

and

r_2

is neither intersecting nor touching any of the circles, if

View answer and explanation

Correct option: B

0<\mathrm{C}_1 \mathrm{C}_2<\left|r_1-r_2\right|

Option B (

0<\mathrm{C}_1 \mathrm{C}_2<\left|r_1-r_2\right|

) is correct because it represents the condition where one circle is completely inside the other, and the radical axis lies outside both circles.
