Explanation

PaaS (Platform as a Service) is the best fit because the cloud provider manages all underlying infrastructure - servers, operating systems, patching, and networking - while the company simply deploys and manages its application and data. This meets the requirement of 'no infrastructure administration.' PaaS platforms also provide built-in scalability (auto-scaling), high availability, and security controls. IaaS (C) still requires the customer to manage VMs, OS updates, and configuration, so infrastructure administration is still needed. A hybrid solution (B) retains on-premises components, which contradicts a full cloud migration and still involves infrastructure management. SaaS (D) delivers pre-built third-party software; you cannot migrate and run your own custom web application on a SaaS model.
