Limiting molar conductivity of \( \mathrm{NH}_{4} \mathrm{OH} \) (i.e. \( \left(\Lambda_{\mathrm{m}}^{\circ}\right) \) \( \left(\mathrm{NH}_{4} \mathrm{OH}\right) \)) is equal to
(A) \( \Lambda^{\circ}{ }_{\mathrm{m}}\left(\mathrm{NH}_{4} \mathrm{OH}\right)+\Lambda^{\circ}{ }_{\mathrm{m}}\left(\mathrm{NH}_{4} \mathrm{Cl}\right)-\Lambda^{\circ} \mathrm{m}(\mathrm{HCl}) \)
(B) \( \Lambda^{\circ} \mathrm{m}\left(\mathrm{NH}_{4} \mathrm{Cl}\right)+\Lambda_{\mathrm{m}}^{\circ}(\mathrm{NaOH})-\Lambda_{\mathrm{m}}^{\circ}(\mathrm{NaCl}) \)
(C) \( \Lambda^{\circ}{ }_{\mathrm{m}}\left(\mathrm{NH}_{4} \mathrm{Cl}\right)+\Lambda^{\circ} \mathrm{m}(\mathrm{NaCl})-\Lambda^{\circ}{ }_{\mathrm{m}}(\mathrm{NaOH}) \)
(D) \( \Lambda^{\circ} \mathrm{m}(\mathrm{NaOH})+\Lambda_{\mathrm{m}}^{\circ}(\mathrm{NaCl})-\Lambda_{\mathrm{m}}^{\circ}\left(\mathrm{NH}_{4} \mathrm{Cl}\right) \)
