Answer:
C and D
C. Stress caused rock layers to bend, and these layers are a small part of a broad gentle fold.
D. Stress caused a fault to form, and these layers dropped down on one side of a fault.
Step-by-step explanation:
Tilts are often caused by faults and folds, so simply the answer is C and D because of the fault that forms and the folds that occur. Faults and folds are the only causes for rock to tilt like that. So as a result the answer again is C and D!
Hope this helps :)
