Why each option

The diagram depicts a multiple hierarchical level campus backbone design, which uses layered cross-connect tiers to provide scalable, organized connectivity across a campus.

AMultiple one level backbone designs

Multiple one-level backbone designs would each be flat and single-tier, with no hierarchical layering between cross-connect levels across the campus.

BMultiple hierarchical level campus backbone designCorrect

A multiple hierarchical level campus backbone design uses more than one tier of cross-connects - typically a main cross-connect (MC), intermediate cross-connect (IC), and horizontal cross-connect (HC) - arranged hierarchically. This structure allows large campus environments to scale connectivity between buildings and floors in a standardized way. ANSI/TIA-568 defines this hierarchical model as the foundation for enterprise campus cabling topology.

CPoorly designed single level campus backbone design

A single-level backbone, whether poorly or well designed, has only one tier of cross-connects and does not reflect the multi-level hierarchy shown.

DWell laid out single level campus backbone design

A well-laid-out single-level design describes a flat topology with a single cross-connect layer, not a design with multiple hierarchical tiers.

EMulti level campus design ready for an easy separation into 3 single level designs

The ability to separate the design into single-level components is a characteristic, not the primary classification - the design is fundamentally hierarchical and multi-level.
