Which of the following is not the correct match for equivalent weight :-

• A
  $KMnO_4 + KI \xrightarrow{OH^{\ominus}} E_{KI} = \frac{M}{6}$
• B
  $Cl^{\ominus} + ClO_3^{\ominus}$ $\xrightarrow{OH^{\ominus}} Cl_2$ $\rightarrow E_{Cl_2} = \frac{M}{5} \times 3$
• C
  $KHC_2O_4 \cdot H_2C_2O_4$ (As reducing agent) $\rightarrow E = \frac{M}{4}$
• D
  $KHC_2O_4 \cdot H_2C_2O_4$ (As acid) $\rightarrow E = \frac{M}{4}$
