8. Does the following report make sense? LSZH VRB02KT 5000 MIFG 02/02 Q1015 NOSIG

The report is nonsense, because it is impossible to observe a meteorological visibility of 5 km if shallow fog is reported

The report would never be seen, because shallow fog is not reported when the meteorological visibility is more than 2km

The report is possible, because shallow fog is defined as a thin layer of fog below eye level

The report is not possible, because, with a temperature of 2°C and a dew point of 2°C there must be uniform fog
