DRM systems typically involve encryption and licensing mechanisms that authenticate users and enforce access restrictions, making it particularly effective for protecting movies, music, and software from unauthorized distribution and consumption. Therefore, when Faruq embeds DRM in the movie file, it ensures that only customers who have the proper authorization can view the content, aligning perfectly with the goal of restricting access to the film.

While options like watermarking, Data Loss Prevention (DLP), and authentication tokens each serve important roles in security and copyright protection, they do not provide the comprehensive control over viewing rights and distribution that DRM offers. Watermarking can deter piracy but does not prevent it. DLP focuses on preventing unauthorized data transfer rather than access management for viewing, and authentication tokens are useful for verifying user identity but do not enforce viewing restrictions on the media itself. Thus, DRM stands out as the
