I'm seriously about to commit mass homicide. My mind does NOT make numbers. Okay, here are the answer choices. I have no clue how to work this godforsaken website yet, so the answers are A,B,C and D respectively. God help me.

since this is a circle equation, and it seems to be in x^2 + y^2 = r^2 form the center is the origin. a and b are basically the same, so its not them. I don't really get this stuff either, but the equation is probably not for ellipses. D.
