Observe the following aqueous solutions of same compound. All the measurements are made at same wavelength and same temperature. Solution A: The transmittance of $0.1 \mathrm{mol} \mathrm{dm}^{-3}$ using 1 cm cell is 0.5 . Solution B: The optical density $0.5 \mathrm{mol} \mathrm{dm}^{-3}$ is measured using 1 mm cell. Solution C: The transmittance of this solution is 0.1. The optical density of these solutions follow the order. $(\log 20=1.3010 ; \log 30=1.4771, \log 50=$ 1.6990
(a)A $>$ B $>$ C
(b)B $>$ C $>$ A
(c)B $>$ A $>$ C
