Answer: (A)

Maintenance is the broad set of actions that keep a piece of equipment ready for use or restore it to service after issues. It covers everything from routine servicing and inspections to repairs, overhauls, and any necessary modifications, as well as confirming the item still meets required standards (condition verification). In short, maintenance encompasses all activities needed to retain or restore serviceability. Operation means using the item; Calibration focuses on ensuring measurement accuracy; Inspection is one activity within maintenance. So the complete description of all those actions is maintenance.
