Sparkling Tiles sells tiles and flooring solutions online. They have a main office in the city and a datacenter in the suburbs. The datacenter location is not an office and hosts many servers which, in case of an outage, would be connected to an alternate power generator.

What is wrong with Sparkling Tiles' plan?

a$.$ The main office should be split in two to reduce the likelihood of a disaster

b$.$ The servers should be hosted in the same building as the office, no matter where

c$.$ The datacenter should allow tb host some employees in case of a disruption at the main office

d$.$ The datacenter should be in the city as close to the office as possible
