Explanation
MTBF (Mean Time Between Failures) is exactly what the definition states: the average elapsed time a system or component operates continuously without failing, measured during operation or testing. Option A is correct because this is the standard, universally accepted definition used in reliability engineering and quality assurance.
Option B is wrong simply because the definition given is accurate - there is no distortion or inversion of the concept.
Memory tip: Think of MTBF as the "good news" metric - it measures how long something works, not how long it takes to fix. If you contrast it with MTTR (Mean Time To Repair), the pair becomes easy to remember: MTBF = uptime between failures, MTTR = downtime to recover. Higher MTBF = more reliable system.
