Redox Reactions and Electrochemistry: JEE Main 2026 Chemistry question

Consider the following data. Electrolyte — $\Lambda^\circ_m$ (S cm$^2$ mol$^{-1}$): $\mathrm{BaCl_2}$ — $x_1$; $\mathrm{H_2SO_4}$ — $x_2$; $\mathrm{HCl}$ — $x_3$. $\mathrm{BaSO_4}$ is sparingly soluble in water. If the conductivity of the saturated $\mathrm{BaSO_4}$ solution is $x$ S cm$^{-1}$ then the solubility product of $\mathrm{BaSO_4}$ can be given as (Here $\Lambda_m=\Lambda^\circ_m$)
