Spectroscopy
Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance?

None of these
Because absorbance is proportional to the concentration of the analyte, whereas %T is not
Because %T cannot be measured as accurately as absorbance
Because %T is dependant on the power of the incident radiation
