Using cuvettes of 0.5 cm path length, a $10^{-4} \mathrm{M}$ solution of a chromophore shows $50 \%$ transmittance at certain wave length. The molar extinction coefficient of the chromophore at this wave length is $(\log 2=0.301)$
(a)$1500 \mathrm{M}^{-1} \mathrm{cm}^{-1}$
(b)$3010 \mathrm{M}^{-1} \mathrm{cm}^{-1}$
(c)$5000 \mathrm{M}^{-1} \mathrm{cm}^{-1}$
(d)$6020 \mathrm{M}^{-1} \mathrm{cm}^{-1}$
