List.l (Substance)	List II (Equivalent weight)
A $\mathrm{Na}_2 \mathrm{CO}_3$	I. $\frac{M}{5}$
B $\mathrm{KMnO}_4 / \mathrm{H}^{+}$	II. $\frac{M}{3}$
C $\mathrm{K}_2 \mathrm{Cr}_2 \mathrm{O}_7 / \mathrm{H}^{+}$	III. $\frac{M}{2}$
D $\mathrm{KMnO}_4 / \mathrm{H}_2 \mathrm{O}$	IV. $\frac{M}{6}$

( $M=$ Formula weight)

The correct answer is

A-III, B-I, C-IV, D-II

A -III, B -IV, C-I, D-II

$\mathrm{A}-\mathrm{II}, \mathrm{B}-\mathrm{III}, \mathrm{C}-\mathrm{IV}, \mathrm{D}-\mathrm{I}$
