A screen reader is a software application designed specifically to assist visually impaired or blind users by converting text displayed on a screen into synthesized speech or braille output. This technology enables users to navigate content on a computer or mobile device by reading aloud the text, allowing them to access information, use applications, and interact with web content effectively. The key functionality of a screen reader includes interpreting user interface elements, providing auditory descriptions of visual content, and facilitating efficient navigation through keyboard commands. This makes option B the accurate choice regarding the definition and purpose of screen readers.

The other options describe tools or services that do not pertain to the primary function of a screen reader. For instance, creating web pages, magnifying text, or providing web hosting services do not address the needs of visually impaired users in the same way a screen reader does.
