Using a child theme in WordPress offers the significant advantage of allowing users to update the parent theme while preserving any custom modifications made. When a parent theme is updated, all the changes made directly to it may be lost, resulting in the need to redo customizations or, worse, having a website that doesn't function correctly after the update. A child theme is a separate theme that inherits the functionality and styling of the parent theme, meaning you can make modifications and custom adjustments within the child theme files. This ensures that updates to the parent theme do not interfere with the customizations, thereby maintaining the integrity of the website design and functionality over time.

The other options highlight aspects of WordPress that are not directly related to child themes. For instance, while it's true that some optimizations might improve website speed, a child theme itself does not inherently affect website speed. Similarly, dedicated hosting is governed by where the website is hosted rather than how themes are configured. User role management is a feature of WordPress that can be managed regardless of whether a child theme is used, and thus is unrelated to the specific benefits of using a child theme.
