(A) Molarity is defined as the number of moles of solute per unit volume of solution $(M = \frac{n}{V})$. Since volume $(V)$ of a solution changes with temperature due to thermal expansion or contraction,molarity is temperature-dependent. In contrast,molality,mole fraction,and weight fraction are based on mass,which remains constant regardless of temperature changes.
