Answer:
Letter C
Explanation:
The correct answer is a base-isolated building.
That's because one of the engineering achievements in dealing with earthquakes is to "separate" the building (or structure) from the horizontal components of the ground movement by interposing a layer with low horizontal rigidity between the structure and the foundation, resulting in interposition of a deformable layer, reducing the frequency of vibration itself, thus helping to deal with earthquakes.
