Answer 2

Answer:

option c is correct ■

When a solution of ethanol is heated with potassium permanganate, the pink color of solution disappear because of strong oxidizing agent as KMnO4, which oxidizes ethanol to ethanoic acid.

CH3−CH2OH KMnO4  CH3COOH

K2Cr2O7 and KMnO4 can convert ethanol to ethanoic acid, oxalic acid is H2C2O4 which can not convert the same.
