Answer:


(x + 3)^2 + (y- 2)^2 = 4

Explanation:

A circle which has center at point(a,b) on coordinate plane and its radius is r, then its equation is represented by

(x-a)^2 + (y-b)^2 = r^2

______________________________________

In the problem

we have

center as (-3,2) while radius is 2 units.

Thus, it equation can be written based on above discussion as

a = -3, b = 2 r =2


(x-a)^2 + (y-b)^2 = r^2 \\(x-(-3))^2 + (y- 2)^2 = 2^2\\(x + 3)^2 + (y- 2)^2 = 4

thus, correct choice is option third.
