For the Method of Continuous Variation,which Is NOT True

For the method of continuous variation,which is NOT true?

A) The method of continuous variation allows for the determination of stoichiometry of a complex.
B) Corrected absorbance is the measured absorbance for the complex less the absorbance for unreacted ligand and central metal.
C) Maximum absorbance is reached at the composition corresponding to the stoichiometry of the predominant complex.
D) The total concentration for various ratios of P and X must be constant.
E) Maximum absorbance when the mole fraction X equals 0.75 is indicative of a complex with the chemical formula of PX₃.
