ANS:C - molality

The number of gram moles of solute dissolved in 1 kg of solvent is called its molality. Molality (symbolized as 𝑚m) is defined as the number of moles of solute per kilogram of solvent. It is preferred over molarity in many situations, especially when temperature changes occur because the mass of the solvent remains constant.
