Explanation

NOTE: The marked answer A (chmod g+t /shared) appears to be an exam error. The correct answer for this scenario is D: 'chmod g+s /shared'. Setting the setgid bit on a directory causes all new files and subdirectories created within it to inherit the group ownership of the parent directory (Admins). This ensures all shared content maintains consistent group attributes, allowing every Admins group member to read and write files regardless of who created them. The sticky bit (g+t) serves a different purpose and is not the right tool here.
