(1) If both Assertion (A) and Reason (R) are True and the Reason \( (\mathrm{R}) \) is a correct explanation of the Assertion \( (\mathrm{A}) \).
(2) If both Assertion (A) and Reason (R) are True but Reason (R) is not a correct explanation of the Assertion (A).
(3) If Assertion (A) is True but the Reason (R) is False.
(4) Assertion (A) is False but Reason (R) is True.
Assertion (A): One molal solution prepared at \( 20^{\circ} \mathrm{C} \) will retain the same molality at \( 100^{\circ} \mathrm{C} \), provided there is no loss of solute or solvent on heating.
Reason (R): Molality is independent of temperature.
