Explanation

PaaS (Platform as a Service) is correct because it provides a managed environment where developers deploy applications without touching the underlying OS, runtime patches, or server infrastructure - the cloud provider handles all of that. IaaS (D) is wrong because it gives you full control over the OS and infrastructure, which is the opposite of what's needed here. SaaS (B) is wrong because it delivers finished software to end users, not a deployment platform for engineers. DaaS (A) - Desktop as a Service - is wrong because it streams virtual desktops, not application deployment environments.

Memory tip: Think of the layers - IaaS = I manage the OS, PaaS = Provider manages the OS (I just bring my app), SaaS = Someone else built the whole app. The question says "cannot manage the OS" → that's the middle layer → PaaS.
