Which out of the following is a correct equation to show change in molar conductivity with respect to concentration for …

\({\Lambda }_{\mathrm{m}}^{2}\mathrm{C}-{\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}^{∘2}+{\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}{\Lambda }_{\mathrm{m}}^\circ =0\)

\({\Lambda }_{\mathrm{m}}-{\Lambda }_{\mathrm{m}}^\circ +{\mathrm{AC}}^{\frac{1}{2}}=0\)

\({\Lambda }_{\mathrm{m}}-{\Lambda }_{\mathrm{m}}^\circ -{\mathrm{AC}}^{\frac{1}{2}}=0\)

\({\Lambda }^{2}{}_{\mathrm{m}}\mathrm{C}+{\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}^{{∘}^{2}}-{\mathrm{K}}_{\mathrm{a}}{\Lambda }_{\mathrm{m}}{\Lambda }_{\mathrm{m}}^\circ =0\)
