The value of \( \lambda_{\mathrm{m}}^{\infty} \) of \( \mathrm{NH}_{4} \mathrm{Cl}, \mathrm{NaOH} \) and \( \mathrm{NaCl} \) are \( 129.8,248.1 \) and \( 126.4 \quad \mathrm{ohm}^{-1} \quad \mathrm{~cm}^{2} \quad \mathrm{~mol}^{-1} \) respectively. Calculate \( \lambda_{\mathrm{m}}^{\infty} \) for \( \mathrm{NH}_{4} \mathrm{OH} \) solution (in \( \mathrm{ohm}^{-1} \mathrm{~cm}^{2} \mathrm{~mol}^{-1} \) )
(A) \( 215.5 \)
(B) \( 251.5 \)
(C) \( 244.7 \)
(D) \( 351.5 \)
