D.
It lists and catalogs all valid data file copies, backup pieces, and archived logs that exist in all directory paths with the prefix /disk1/backups and their subdirectories.
Explanation:
If you have data file copies, backup pieces, or archived logs on disk, then you can catalog them in the recovery catalog with the CATALOG command.
The following command catalogs all files in all of these directories, because /disk1/backups is a prefix for the paths for all of these directories:
CATALOG START WITH ‘/disk1/backups’;
To catalog only backups in the /disk1/backups directory, the correct command is as follows:CATALOG START WITH ‘/disk1/backups/’;
