The cloud service model that allows users to rent virtualized computing resources over the internet is IaaS, which stands for Infrastructure as a Service. IaaS provides virtualized physical computing resources over the Internet and allows users to manage their infrastructure without having to invest in physical hardware.

Here's a brief overview of the options provided:

1. IaaS (Infrastructure as a Service): This model provides users with virtualized computing resources such as virtual machines, storage, and networks. Users can rent these resources and scale them according to their needs.

2. PaaS (Platform as a Service): This model provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure of the underlying layer.

3. On-premises: This refers to the traditional model where hardware and software are purchased and installed locally, not over the cloud.

4. SaaS (Software as a Service): This model delivers software applications over the internet on a subscription basis, eliminating the need for installation and maintenance on local machines.

In conclusion, the correct answer is IaaS.
