A mixture of methionine (A), glutamic acid (B) and lysine (C) is separated by paper electrophoresis in two  experiments, one at $pH=1$ and one at $pH=12.$  After the separation, the paper strips are treated with ninhydrin to reveal the location of amino acids (Purple spots). Which of the following correct match is of strips with appropriate $pH$?

At $pH-1$ (A) Methionine exist as $+1$ cation 
                        (B) Glutamic acid exist as $+1$  cation
                         (C)  Lysine exist as $+2$ cation
Electrophoretic mobility is directing proportional to magnitude of change   
At  $pH-12$ Methionine exist as $-1$ anion  
                             Lysine exist as $-1$ anion
                    Glutamic acid exist as  $-2$ anion
