Standard cell voltage for the cell \( \mathrm{Pb}\left|\mathrm{Pb}^{2+} \| \mathrm{Sn}^{2+}\right| \mathrm{Sn} \) is \( -0.01 \mathrm{~V} \). If the cell is to exhibit \( E_{\text {cell }}=0 \), the value of \( \left[\mathrm{Sn}^{2+}\right] /\left[\mathrm{Pb}^{2+}\right] \) should be antilog of \( - \)
(a) \( +0.3 \)
(b) \( 0.5 \)
(c) \( 1.5 \)
(d) \( -0.5 \)
