Your answer should be circle D.
To find this, you first need to understand the equation that has been presented to you.
(x-h) squared + (y-k) squared = radius squared
(x-2) squared + (y+5) squared = 4
In these, 2 and -5 are h and k, meaning that they are the center of the circle. This immediately eliminates A, B, and E. Now, since the radius is also squared, you have to find the square root. In this case, it's 2, so the radius is 2.
Hope this helps!
