Best answer
The correct option is (c) Methyl alcohol

Best explanation: Terephthalic acid is converted into its dimethyl ester by treating it with methyl alcohol. At high temperature, TPA crystals constantly dissolve and reform which increases the release of 4-formylbenzoic acid in solution where oxidation can be completed.
