The same amount of Fe3+and Cd2+ are colored in the same volume of solution by developer, measured by Absorbance Photometry. The former uses a 2cm cuvette and the latter uses a 1cm cuvette. If gain the same absorbance, the Molar Absorptivity Coefficient of the two colored complexes is 
A、Basically the same
B、Fe3+is as twice as Cd2+
C、Cd2+is as twice as Fe3+
D、Cd2+is as four times as Fe3+
