319139 The correct relation between elevation of boiling point and molar mass of solute is

319140 Read Assertion and Reason carefully to mark the correct option given below.
Assertion :
Elevation in boiling point is inversely proportional to molar mass of solute.
Reason :
It is because elevation in boiling point is directly proportional to molality.
