Answer: D

Explanation:

According to IBM documentation1, one of the considerations when setting the number of parallel, database backup streams with the SET DBRECOVERY command is that each stream requires its own volume. The device class that is specified for automatic backups must have enough volumes to accommodate the number of streams that are specified. If there are not enough volumes available, some streams might fail.
