正解:B
Disaster Recovery (DR) focuses on restoring IT and business services to support essential operations after a disruption.
ISACA defines:
"The primary objective of disaster recovery is the timely restoration of critical IT systems and services necessary to support business operations." Recovery of financial records or facilities are secondary components.
Therefore, B. Restore critical business and IT services is correct.
