Software as a Service (SaaS)

Explanation:

Software as a service (SaaS) allows users connected to cloud-based applications over the Internet and use them. Some common examples are email, calendars and office tools (such as Microsoft Office 365).

SaaS offers a comprehensive software solution that is acquired from a cloud service provider through a pay-per-use model. It is possible to rent the use of an application for the organization and users connect to it through the Internet, usually with a web browser. All underlying infrastructure, middleware, software and application data are located in the provider's data center. The service provider manages the hardware and software and, with the appropriate service contract, will also guarantee the availability and security of the application and data. SaaS allows an organization to get started and can run applications with a minimal initial cost.

what do you mean.why did u repeat the question.

the correct answer option is b. a single paragraph.

explanation:

when you are thinking about paragraph​ topics, you should always choose a subject that can be adequately addressed in a single paragraph.

a paragraph is a piece of writing consisting of a few sentences that deal with a single theme. it has only a single idea that the paragraph revolves around and talks about.

so a paragraph topic must be chosen wisely where a single idea can be communicated in a single paragraph.
