Answer:
The placement of legend does not follow the principles of map hierarchies.
Explanation:
A is not correct because the title is positioned in the right place.
B is not correct because the placement of inset is right.
C is not correct because there isn't any bibliographic information on this map.
D is correct because the legend is positioned on top of the object that is represented instead of being in a bottom corner and not interfering with the view.
