What are the two MAJOR activities in problem management?

Technical and service are not recognized categories of problem management activities in the ITIL framework.

Resource and proactive are not the two defined major activities - resource allocation is a consideration within activities, not a standalone category.

Reactive and technical is incorrect because 'technical' is not one of the two major activities; the correct pairing is reactive and proactive.

ITIL defines problem management as having two distinct major activities: reactive problem management, which focuses on identifying root causes and providing workarounds or permanent fixes after incidents have occurred, and proactive problem management, which focuses on identifying and preventing problems and incidents before they happen by analyzing trends and historical data.
