(B) center: (-2, 2); radius: 4; area: 2 \(\pi \)
(C) center: (2, -2); radius: 4; area: 4 \(\pi \)
(D) center: (-2, 2); radius: 2; area: 4 \(\pi \)
(E) center: (-2, 2); radius: 4; area: 4 \(\pi \)
(A) center: (2, -2); radius: 2; area: 4 \(\pi \)
(B) center: (-2, 2); radius: 4; area: 2 \(\pi \)

If the radius is \(2\) then the area will be \(4π\) for a circle. With this, we can reject options B C E
For a Circle with the equation \((x – h)^2 + (y – k)^2 = r^2\) where (h, k) is the center of the circle and r is its radius.
Comparing this with the given equation, \((x + 2)^2 + (y - 2)^2 = 4\)
Center \((-2,2)\) & radius \(= 2\) and area \(= 4π\)
Answer D
