Explanation

The correct fix is setfacl -m g:finance:rw file, which uses POSIX Access Control Lists (ACLs) to grant read/write access to the finance group without altering the base file permissions that already allow IT access. Option A (chattr +i) makes the file immutable - no one could write to it. Option B (chown it:finance) can only assign one group as the owning group. Option C (chmod 666) gives read/write to all users on the system, which violates the requirement to limit access to IT and finance only. ACLs allow multiple groups to be granted fine-grained permissions simultaneously.
