hope I'm right but either 2 or 4 i can kinda go either way
In the problem, it says that the center of the circle is at point (a,b) and has a radius of length m. In this case, the standard form of the circle is represented by the equation (x-h) ^2 + (y-k)^2 = r^2. Upon substitution, (x-a) ^2 + (y-b)^2 = m^2.This is equal to x2 - 2ax + a2 + y2 -2by + b2 = m2. The equation that is similar here is A
