Correct answer & explanation
✓
Automated backups with a retention period greater than 0.
Automated backups with a retention period greater than 0 are required for point-in-time recovery (PITR) in Amazon RDS. Option A is incorrect because deletion protection prevents accidental deletion but does not enable PITR. Option B is incorrect because read replicas are used for read scaling and disaster recovery, not for PITR. Option D is incorrect because Multi-AZ provides high availability but is not a prerequisite for PITR.
