The complex numbers shown have the form:

By definition, the distance can the distance of the complex number from the origin on the complex plane can be calculated with the formula shown below:

Substitute values of each option. Then:
1) 
2) 
3) 
4)
(CORRECT OPTION)
Answer:
-2
Step-by-step explanation:
since the parabola opens upwards, the minimum is at the vertex of the parabola and the maximum is infinity, because the lines of a parabola goes on forever
you look for the smallest x value for the parabola and since you can see that the vertex of the parabola lies on x=-2, the minimum value of the function is -2.
Hope that helps :)
