Best answer
Correct option is (b) ethanoic acid

Explanation: Aldehydes are easily oxidised to carboxylic acids with same number of carbon atoms, in the presence of oxidising agents like HNO3, KMnO4, etc. This is because of the presence of H atom next to CO group, which can be easily converted to OH group with any bond cleavage.
