Final Answer : C, Explanation :  MTBF (Mean Time Between Failures) is the average time between one failure and the next, while FR(N) (Failure Rate per Unit of Time) is the number of failures that occur in a specific period of time. These two concepts are related through their inverse relationship:MTBF = 1/FR(N)Therefore, the MTBF is the reciprocal of the FR(N).
