Explanation

Infrastructure as a Service (IaaS) is the correct answer here. With IaaS, an external provider supplies the underlying infrastructure - servers, networking, and storage - while the customer retains responsibility for the operating system, middleware, and their own applications. Moving internally developed applications to externally hosted infrastructure (reducing on-premises server footprint) is the defining characteristic of IaaS. Platform as a Service (PaaS) would mean the external provider also manages the OS and runtime, leaving only the application code to the customer. Software as a Service (SaaS) means the provider delivers a fully managed application, which does not apply since these are internally developed apps. Storage as a Service addresses only data storage, not application hosting.
