D. Screen readers Images and icons that can explain content, clear and large navigational elements, integrated speech output, and total keyboard accessibility are all design practices that can facilitate the use of screen readers. Screen readers are assistive technology devices that convert digital text into synthesized speech or braille output for individuals who are blind or visually impaired. These design practices ensure that digital content is accessible to users who rely on screen readers to navigate and interact with websites and applications.

I think the wording of this question is a little tricky since it's asking which design techniques will facilitate which assistive technology and doesn't say that all techniques apply. AAC supplements speech or compensates for speech impairments for those with communication disorders. Most of the techniques apply to screen readers.
