Explanation

MTTR (Mean Time To Repair/Recovery) is a time-based metric that measures the average duration required to restore a failed system or component to full operation - making hours the correct format, as it directly expresses elapsed time.

B (Weight) is wrong because MTTR has nothing to do with physical mass; weight is a unit for measuring heaviness, not operational metrics.
C (Fraction) is wrong because MTTR is an absolute duration, not a ratio or proportion (that would apply to metrics like availability percentage).
D (Distance) is wrong because distance (miles/kilometers) measures space, not time.

Memory tip: Think of MTTR as asking "how many hours was the system down?" - it's always answering a how long question, and time is measured in hours (or minutes), never in weight, fractions, or distance.
