E Correct answer
Explanation

RMAN BACKUP command cannot back up online redo log files. RMAN supports backing up datafiles, control files, parameter files (spfile), archivelog files, and even backup sets themselves, but online redo logs are explicitly excluded. This is by design - redo logs are managed through the log switch/archive mechanism, not RMAN backups. Attempting to back them up with RMAN will fail.
