Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Molality of a solution does not change with change in temperature. Reason (R): Molality is expressed in terms of moles of solute per litre of solution. In the light of the above statements, choose the correct answer from the options given below:

  1. (A) is true but (R) is false.
  2. Both (A) and (R) are true and (R) is the correct explanation of (A).
  3. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  4. (A) is false but (R) is true.
