Answer: software as a service (SaaS)

The question asks which cloud service model minimizes the customer's management responsibility. According to the Azure shared responsibility model, SaaS (Software as a Service) places the most responsibility with the cloud provider and the least with the customer. In SaaS, the provider manages the infrastructure, platform, and application software, while the customer is primarily responsible only for their data, user access, and connected devices. This is supported by the community discussion where commenters with high upvotes (5 and 3) confirm C (SaaS) as correct, citing that SaaS minimizes management tasks like provisioning, scaling, patching, and updates. In contrast, IaaS (A) requires the customer to manage the OS, applications, and data, and PaaS (B) requires management of applications and data, both placing more responsibility on the customer than SaaS.
