The correct option is C, anticline.
In structural geology, an up fold in rock layers, where the limbs dip away from the hinge and the oldest strata are typically in the core, is called an anticline. Conversely, a down fold, where the limbs dip towards the hinge and the youngest strata are in the core, is called a syncline. Graben and horst are fault-related structures; a graben is a down-dropped block bounded by normal faults, and a horst is an uplifted block bounded by normal faults.
