Based on the shared responsibility model, which of the following solutions passes the responsibility of patching the OS to the customer?
The correct answer is C. IaaS. Under the shared responsibility model, IaaS customers receive raw virtualized infrastructure and must manage and patch the operating system themselves, unlike higher-level service models where the provider handles OS maintenance.

Why each option
Under the shared responsibility model, IaaS customers receive raw virtualized infrastructure and must manage and patch the operating system themselves, unlike higher-level service models where the provider handles OS maintenance.
In PaaS, the provider manages the underlying OS and runtime environment, so OS patching is the provider's responsibility, not the customer's.
DBaaS is a managed database offering that sits on top of a provider-managed OS, meaning the provider handles OS and database engine patching.
IaaS (Infrastructure as a Service) provides virtualized compute, storage, and networking, but the cloud provider's responsibility stops at the hypervisor layer. The customer is responsible for deploying, configuring, and patching the guest operating system, along with middleware and application layers running above it.
In SaaS, the provider manages the entire stack including infrastructure, OS, and application, leaving the customer responsible only for data and user access.
