- B.The height of the lowest cloud base in a METAR
- C.The lowest altitude where the air temperature reaches 0 degrees C, above which icing becomes possible in visible moisture

C. The lowest altitude where the air temperature reaches 0 degrees C, above which icing becomes possible in visible moisture
Why
Knowing the freezing level helps an operator judge where temperatures aloft could support icing. AIRMET Zulu includes freezing level information for this reason.
