Answer : The correct option is, directly proportional

Explanation :

Formula used for lowering in freezing point :

$\Delta T_f=k_f* m\\\\T^o_f-T_f=k_f* m$

where,

$\DeltaT_f$ = change in freezing point

T^o_f = freezing point of pure solvent

T_f = freezing point of solution

k_f = freezing point constant

m = molality

From this we conclude that the reduction in the freezing point of a solution is directly proportional to the molal concentration.

Hence, the correct option is, directly proportional
