The correct answer is D. SaaS.
SaaS stands for Software as a Service. It is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted by the service provider. SaaS is a popular model for businesses of all sizes, as it offers a number of advantages over traditional on-premises software, including:
- Reduced costs: SaaS is a pay-as-you-go model, which can save businesses a significant amount of money on software licensing costs.
- Increased agility: SaaS applications are typically updated more frequently than on-premises applications, which can help businesses stay ahead of the competition.
- Improved security: SaaS applications are typically hosted in secure data centers, which can help businesses protect their data from security threats.
One of the benefits of SaaS is that it allows service providers to offer customization options to their customers. This can be done by providing a module that allows customers to add their own branding, content, and functionality to the application. This can be a valuable feature for businesses that want to differentiate their offering from the competition.
