A
$2 H _2 O _2 \rightarrow 2 H _2 O + O _2$
B
$2 NO _2+ H _2 O \rightarrow HNO _3+ HNO _2$
C
$MnO _4^{-}+4 H ^{+}+3 e ^{-} \rightarrow MnO _2+2 H _2 O$
D
$3 MnO _4^{2-}+4 H ^{+} \rightarrow 2 MnO _4^{-}+ MnO _2+2 H _2 O$
Solution:
Correct answer is (c) $MnO _4^{-}+4 H ^{+}+3 e ^{-} \rightarrow MnO _2+2 H _2 O$
