Explanation

IaaS (Infrastructure as a Service) gives users direct control over virtualized hardware resources - compute, storage, and networking - without owning physical hardware. This is its defining trait: you manage the OS, middleware, and everything above the hardware layer, while the provider manages the physical infrastructure beneath.

A is wrong - APIs are a feature of all cloud service models (IaaS, PaaS, SaaS), not a distinguishing characteristic of IaaS specifically.
C is wrong - Automatic software updates are a hallmark of SaaS, where the provider manages the full software stack so users never patch anything.
D is wrong - Managed database services describe PaaS (e.g., AWS RDS), where the platform abstracts away infrastructure management so you focus only on your data.

Memory tip: Think of the "I" in IaaS as "I control the hardware (virtually)." If you're provisioning VMs and configuring your own OS, you're in IaaS territory - maximum control, maximum responsibility.
