Show answer & explanation
Correct answer: B
Concept
An acronym is formed from the initial letters of a standardized name. To test an acronym–expansion pair, compare every significant word in the proposed expansion with the accepted full form and its technical domain.
Application
GPS denotes the satellite-based Global Positioning System, so the words in this pair align with the accepted name.
GSM denotes Global System for Mobile Communications. The proposed word “Management” replaces the mobile-communications part of the accepted name.
SIM denotes Subscriber Identity Module, the module that stores subscriber identity and authentication information.
WiMAX denotes Worldwide Interoperability for Microwave Access, a broadband wireless-access technology.
Contrast
GPS is associated with positioning and navigation.
GSM is associated with mobile communications, not management.
SIM is associated with subscriber identity.
WiMAX is associated with interoperable microwave-based wireless access.
Result
Therefore, the incorrectly matched pair is GSM – Global System for Management.
