In earthquake$-$resistant building construction, what role does base isolation play in civil engineering?

A$)$ It involves elevating the entire building above ground level.

B$)$ It helps to absorb and dissipate seismic energy, reducing the impact on the structure.

C$)$ It focuses on increasing the weight of the building to stabilize it during earthquakes.

D$)$ It involves using flexible materials for construction to allow the building to sway with the seismic waves
