Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : At 10…C, the density of a 5 M solution of KCl [atomic masses of K & Cl are 39 & 35.5 g mol^…1 respectively], is 'x' g ml^…1. The solution is cooled to …21…C. The molality of the solution will remain unchanged. Reason (R) : The molality of a solution does not change with temperature as mass remains unaffected with temperature. In the light of the above statements, choose the correct answer from the options given below :

Option A. Molality and Mass are temperature Independent so on changing temp., molality and mass remain unchanged.
