Solution
The correct option is C autocatalyst In
the tit-ration between oxalic acid and acidified potassium permanganate, the
manganous salt formed during the reaction and catalyses the reaction. The
manganous salt acts as auto catalyst because the rate of reaction depends on the manganous ions formed,so manganous ions catlyze the reaction. Hence option C is correct.
