These three are the recognized ITIL structures; IT Help Desk (3) is not a formal ITIL category.

This option includes IT Help Desk (3), which is not formally defined by ITIL, and excludes Follow the Sun (4), which is a valid and recognized ITIL Service Desk structure.

This option includes IT Help Desk (3), which is not an ITIL-recognized structure, and excludes Virtual Service Desk (2), which is one of the three formal ITIL Service Desk structures.
