Do not over-think this!  It ‘should’ be a simple question.  I state this because I’ve had students feel as it was a trick question. It is not!  Just think DALR! You have a surface temperature of 30 degrees C.  Your dewpoint is 10 degrees C.   Assuming air parcels are lifted upward (adiabatic cooling), at what altitude will the air parcels reach 100% relative humidity, condense, and begin to form a cloud?
