To find the midpoint of line FG, we have to use the following midpoint formula , which is

In the given question,
x1= -5, y1= -3 , x2=-3, y2=3
Substituting the values of x1,y1,x2 and y2 in the formula of the midpoint, we will get

So the midpoint of the given line is (-4,0) and hence the correct option is the first option .
