A. \(\displaystyle x^2+y^2-24x-2y-20=0\)

B. \(\displaystyle x^2+y^2-24x-2y-4=0\)

C. \(\displaystyle x^2+y^2-12x-2y-11=0\)

D. \(\displaystyle x^2+y^2-4x-2y+1=0\)

E. \(\displaystyle x^2+y^2-4x-2y+4=0\)

I don't know how to do it. Judging by the center of the circle, the answer must be either D or E. However, when I checked both of them with Desmos, neither circles even touches the line. How should I do it? Even if there's no right option, I would still like to know in case I encounter this kind of question again.
