C

Explanation:

The standard form of the color(blue)"equation of a circle"equation of a circle is.

color(red)(bar(ul(|color(white)(2/2)color(black)((x-a)^2+(y-b)^2=r^2)color(white)(2/2)|)))
where (a ,b) are the coordinates of the centre and r, the radius.

"the centre "=(2,-5)" and radius "=12

rArra=2,b=-5" and "r=12

substituting into the equation gives.

(x-2)^2+(y-(-5))^2=12^2

rArr(x-2)^2+(y+5)^2=144toC
