The graph is a circle, centered at the origin, with radius=4.
We know that we can write the equation of a circle with radius r and center (a,b) as :

.
Thus, substituting (a, b) with (0, 0) and r with 4, we have:

.
The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:

,
we would still have the same roots.
Thus, the equation of the circle can be written as :

.
Answer: B
Equal to 1, and you'll just add a 4 and that will make it 4/4 and like both are the same numbers it will become 1 whole
