Show answer & explanation
Correct answer: C
CONCEPT
An operating system is system software that manages hardware resources and executing programs, and provides controlled services through which users and applications interact with the computer.
Application software performs task-specific work for a user on top of the services supplied by the operating system.
APPLICATION
Statement A describes spell-checking, a document-editing feature normally implemented by a word-processing application.
Statement B describes process management: the operating system creates, schedules, coordinates, and terminates executing processes.
Statement C describes a user-interface service: an operating system exposes mechanisms such as a command-line interface or graphical interface for interaction.
CONTRAST
A and B only combines an application-level text feature with an operating-system process service and leaves out the interface service.
A and C only combines an application-level text feature with an operating-system interface service and leaves out process management.
B and C only contains the two operating-system responsibilities while excluding the application-level spelling feature.
A, B and C only includes the application-level spelling feature alongside the two operating-system responsibilities.
RESULT
Therefore, the functions of an operating system among the listed statements are B and C only.
