Answer:
Option (A)
Explanation:
An anticline is defined as a structural trap that is the arch-like shape and are usually formed due to the compressional stress. In an anticline, the older rocks are present towards its interior and the younger rocks are formed towards the exterior.
The anticlines have resulted from previously existed horizontal rock layers that undergo compressional stress. They can be identified by the orientation of their fold limbs as the limbs dip away from the hinge of the fold.
These anticlines have great importance in the field of geology as these are the structures in which the oil and natural gas are being trapped.
Thus, the correct answer is option (A).
