A. B. C. D.D.
The given command "echo "Monday through Friday" > /production_docs/days" should write the output "Monday through Friday" to a file called "days" inside the "/production_docs" directory. However, the command has failed to execute, and the user has provided the output of the "ls -l" command for the "/production_docs" directory and the "days" file.
The output shows that the "/production_docs" directory is owned by "root" and the "production" group, and has read and execute permissions for the group, but no write permissions. The "days" file is owned by "production" and the "production" group, and has read and write permissions for the group.
To fix the issue, the user needs to be able to write to the "days" file. Option A, "chmod g+w production" would change the permissions on the "production" file, but it would not grant write permission to the user who needs it.
Option B, "chgrp root production_docs/days" would change the group ownership of the "days" file to "root", but it would not grant write permission to the user who needs it.
Option C, "chmod g+S production" would set the GUID on the "production" directory, but it would not grant write permission to the user who needs it.
Option D, "chown production" is incorrect, as it would change the ownership of the "production_docs" directory to the user "production", but it would not grant write permission to the user who needs it.
Therefore, the BEST option to fix the issue would be to execute the command "chmod g+w /production_docs/days" to add write permission for the group to the "days" file. This would allow the user in the "production" group to write to the file.
