Why are very high and very low absorbance measurements considered inaccurate? (check all that apply)

a) at high absorbances, a sufficient amount of light does not reach the detector for an accurate measurement

b) at low absorbances, the transmission is too small for accurate measurement

c) at low absorbances, the difference in the absorbance of the sample and the blank sample is too small for an accurate measurment

d) at high absorbances, the detector is saturated because too much light is reaching the detector for an accurate measurement

e) at high absorbances, the transmission is too high for an accurate measurement
