Which of the following BEST distinguishes an incident from a service request?
This is the core distinction in ITIL 4.
Why this answer
The key distinction is that incidents are unplanned interruptions or reductions in quality, while service requests are predefined, pre-approved, and typically low-risk. Option C is correct. Option A is incorrect because both can be reported by users.
Option B is vague; both may have SLAs. Option D is incorrect because service requests are not necessarily for new services.
