Which of the following is a drawback to using proprietary file formats?

Using proprietary file formats can present accessibility challenges, particularly for individuals with disabilities. Many proprietary formats may not be designed with accessibility in mind, potentially limiting options such as screen reader compatibility or customizable viewing settings. This can hinder a disabled person's ability to access, interpret, and utilize the information contained within those files.

While the other options relate to different facets of file formats, they do not directly address the drawbacks of proprietary formats as effectively. For instance, proprietary formats may offer some advantages in terms of performance or features but can be exclusive to specific software ecosystems, which can lead to accessibility issues. Understanding the implications of using proprietary formats is crucial in ensuring that all users, regardless of their abilities, can access important information.
