4. When using an electronic leak detector, the probe should be moved:

   • A. Quickly across large areas to cover more ground
   • B. Slowly along the bottom of hoses and fittings since refrigerant vapors are heavier than air
   • C. Only around the compressor shaft seal
   • D. Above all system components since refrigerant vapors rise
