Answer:
The hanging wall moves down relative to the footwall at a normal fault.
Explanation:
A is not correct because hanging fault doesn't exist.
B is not correct because at this type of fault the hanging wall and the footwall slide past each other.
C is not correct because at this type of fault the hanging wall moves up relative to the footwall.
D is correct because at this type of fault the hanging wall is moving down relative to the footwall, so the hanging wall is positioned at a lower elevation than the footwall.
