a. fixed-base building.
b. wood-frame building.
c. base-isolated building.
d. brick building.
select the best answer from the choices provided

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.

explanation:

bc blah

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
