MTBF (A) refers to Mean Time Between Failures, measuring the average time between system failures, while RTO (C) stands for Recovery Time Objective, which is the targeted duration for restoring services after an outage, and RPO (D) means Recovery Point Objective, focusing on the maximum tolerable period in which data might be lost.
