Which one of the following is the BEST description of a service request?

ITIL defines a service request as a request from a user for information, advice, a standard change, or access to an IT service. This definition distinguishes service requests from incidents and non-standard RFCs, and they are fulfilled via the request fulfillment process without triggering full change management.

Describing anything a customer wants and is prepared to pay for is too broad and does not align with the specific ITIL definition, which requires the request to be a recognized, pre-approved type.

Service requests are not limited to self-help web interfaces; they can be submitted through any channel such as phone, email, or in person.

Service requests involve pre-approved standard changes by definition and are not the same as low-risk RFCs requiring change manager approval, which follow a different change management path.
