Which of the following best describes a web page?

A web page is best described as a document that can be viewed in a web browser. This definition captures the essence of what a web page is—essentially a digital document that utilizes HTML (HyperText Markup Language) to present content, which can include text, images, videos, and links to other web pages. The primary function of a web page is to be accessed via a web browser, such as Chrome, Firefox, or Safari, allowing users to interact with and consume information online.

The other options do not accurately depict a web page. A standalone software application refers to a program that operates independently and is not accessed through a web browser. An operating system feature relates to capabilities or tools integrated within an operating system itself, which does not pertain to the concept of a web page. Lastly, a database management tool is focused on organizing and manipulating data in databases, which is fundamentally different from the notion of a web page that serves content to users directly through web interfaces.
