Answer:

A, B, C

Solution:

$MnO_{4}^{-} + 5 Fe^{2 +} + 8 H^{+} \to Mn^{+ 2} + 5 Fe^{3 +} + 4 H_{2} O$

$C r_{2} O_{7}^{2 -} + 6 F e^{+ 2} + 14 H^{+} \to 6 F e^{+ 3} + 2 C r^{+ 3} + 7 H_{2} O$

$8 M n O_{4}^{-} + 5 C u_{2} S + 44 H^{+} \to 8 M n^{+ 2} + 10 C u^{+ 2} + 5 S O_{2} + 22 H_{2} O$

$4 C r_{2} O_{7}^{2 -} + 3 C u_{2} S + 44 H^{+} \to 8 C r^{+ 3} + 6 C u^{+ 2} + 3 S O_{2} + 22 H_{2} O$
