A studend gets fingerprints on a cuvette before using it to determine the concentration of a coloured species using its known extinction coefficient. What is the effect on the absorbance and reported concentration ?
A. `{:("Absorbance",,"Reported concentration"),("Increased",,"too law"):}`
B. `{:("Absorbance",,"Reported concentration"),("Increased",,"too high"):}`
C. `{:("Absorbance",,"Reported concentration"),("decreased",,"too low"):}`
D. `{:("Absorbance",,"Reported concentration"),("decreased",,"too high"):}`
