Answer:
(D)
Step-by-step explanation:
From the figure, we have
The coordinates of the point F are: (-4,1).
The coordinates of the point G are: (0,-2)
The coordinates of the point J are: (0,4) and
The coordinates of the point H are: (-4,-2).
Now, the slope of the line FG is :



And, the slope of the line HJ is:



Now, 

which is not possible, thus They are not perpendicular because their slopes are not negative reciprocals.
