Identify the three versions of the MercuryGate TMS.

The correct choice identifies EZVision as one of the three versions of the MercuryGate Transportation Management System (TMS). EZVision is noted for its user-friendly interface and enhanced visibility features, which facilitate effective decision-making and real-time tracking of transportation activities. This version emphasizes ease of use and accessibility, making it an attractive option for organizations looking to streamline their logistics and supply chain management.

In the context of the other choices, LegacyTMS and EZClick may sound relevant but do not accurately represent the official versions or nomenclature typically associated with MercuryGate's offerings. Legacy systems generally refer to older software that might not have the modern capabilities found in updated versions, while EZClick may not be recognized as a formalized version of the TMS within the MercuryGate structure. List Screens, on the other hand, appears to refer to a feature or functionality tied to the software rather than a separate version. Thus, EZVision stands out as an official designation among the versions of the TMS provided by MercuryGate.
