What is a digital service?

A digital service is a service that fully or largely relies on digital products, which makes option A correct. ITIL distinguishes between digital products and digital services while showing that they are closely connected. The digital product is the combination of digital resources designed to offer value. The digital service is the means by which value is co-created with consumers using those products. Option B is closer to the definition of a digital product. Option C describes one type of service interaction, not the general definition of a digital service. Option D refers to a catalogue or representation of available services rather than the service itself. The digital service concept reflects ITIL’s focus on technology-enabled value creation through outcomes, service relationships, and managed access to capabilities.
