which floor would be best for information processing facilities?

In a six-story building, which floor would be best for information processing facilities?

A.
Basement

B.
Ground floor

C.
Third floor

D.
Sixth floor

Explanation:
Information processing facilities should not be located on the top
floors of buildings in case of a fire or in the basements in case of floods. They
should be located at the core of a building to provide protection from natural
disasters or bombs and provide easier access to emergency crewmembers if necessary.
