Answer:

B. (x +5)² +(y -5)² = 9

Explanation:

The standard form equation for a circle with center (h, k) and radius r is ...

(x -h)² +(y -k)² = r²

__

When the center is (h, k) = (-5, 5) and the radius is r = 3, this becomes ,..

(x -(-5))² +(y -5)² = 3²

Simplifying gives ...

(x +5)² +(y -5)² = 9 . . . . . matches choice B
