Explanation

On-premises (D) is correct because responsibility for all layers of the stack - hardware, networking, operating system, middleware, and application - falls entirely on you. No cloud provider shares any portion of that burden. The question's phrasing "all layers" is the decisive clue.

Why the distractors are wrong:

(A) SaaS - The provider manages nearly everything; your responsibility is limited to user access and data configuration, not all layers.
(B) PaaS - The provider handles infrastructure and the runtime environment; you only secure your application and data.
(C) IaaS - The provider secures the physical hardware and virtualization layer; you still share responsibility rather than owning all layers.

Memory tip: Use the phrase "On-premises = On you." The further you move from on-premises toward SaaS, the more responsibility shifts to the provider and the fewer layers you control. If a question says you own every layer, the answer is always on-premises.
