Why each option

A screen reader is an assistive technology whose purpose is to vocalize text and describe graphical elements displayed on a computer screen for blind or visually impaired individuals.

AIt reads text displayed on the screen to blind or visually impaired people.Correct

Screen readers are accessibility tools designed to convert on-screen text and graphical elements into speech or braille output, enabling blind or visually impaired users to interact with and understand the content of a computer display.

BIt reads the parameters of the attached monitors and creates an appropriate X11 configuration.

Reading monitor parameters and creating X11 configurations is a function of display configuration tools and the X server itself, not a screen reader.

CIt displays lines and markers to help people use speed reading techniques.

While there are tools for speed reading, a screen reader's primary purpose is not to display lines or markers for speed reading, but to vocalize content for the visually impaired.

DIt manages and displays files that contain e-books.

E-book managers display and organize digital books, which is a different function from interpreting and vocalizing general screen content for accessibility.
