I think your answer should be D. Deep Ocean. Hope this helps. =^-^=
D. crust and upper mantle
because it is the two uppermost layers that moves the plates to create earthquakes, landslides, etc.
A is wrong because there is another layer in between the two called the upper mantle.
B and C is wrong because they do not contain the crust, the outermost layer of the earth.
If it was my store I would have a camera in every corner of the store to get every angle. So to get the official answer I suggest you to count how many corners there are throughout the store and that will be your answer.
Hope this helps!

If you are in the northern hemisphere, then the angle between Polaris and
your northern horizon is always within about 1/3 degree of your north latitude.
For many purposes, it's close enough to just figure that the elevation of Polaris
above your northern horizon <u>IS</u> your north latitude.
Sadly, it's a different story if you are in the southern hemisphere ... Polaris is
never visible from there at all.
