The correct answer is B. The term "Software as a Service" (SaaS) refers to a cloud computing model where software applications are hosted on remote servers and made available to users over the internet. In this model, users can access and use the software via a web browser or thin client without needing to install the application locally on their devices. When an application is deployed as a SaaS solution, it is installed and maintained on servers centrally managed by the service provider. Multiple users can then access and use the application simultaneously, each with their own unique user accounts and data, without the need for individual installations on their devices. This centralized approach to software deployment and access enables efficient sharing and collaboration among users while minimizing the overhead associated with local installations and maintenance.
