Given the script
create script db_backup_datafile_script
{backup datafile &1, &2 plus archivelog delete input;}
what is the result of running this command?
Run {execute script db_backup_datafile_script using 2;}
A. The script will fail since you instructed RMAN to back up only one datafile rather than two.
B. The script will successfully back up datafile 3 without error.
C. The script will fail since it uses a substitution variable which is not supported.
D. The execute script command will prompt for the value of &2 since it‘s not included in the command.
E. The script will fail because you cannot use the plus archivelog command when backing up database
datafiles.

in a value for the second substitution variable.
