The feature that the app builder should use to solve this issue is component visibility filter. A component visibility filter is a setting that can be applied to a Lightning component on a record page to control when the component is hidden or displayed based on certain conditions. The app builder can use a component visibility filter to hide the component from users with a Marketing profile. Option A is incorrect because detail page layouts are not related to Lightning components, but rather the fields and related lists that appear on record detail pages. Option C is incorrect because field-level security is not related to Lightning components, but rather the access level of fields for different profiles or permission sets. Option D is incorrect because AppExchange is not related to Lightning components, but rather an online marketplace where users can find and install apps and components.
