Answer:
B Organic acids
Step-by-step explanation:
Depending on the conditions of the oxidation, aldehydes will form carboxylic acids. This will happen if the oxidation happens under acidic or alkaline conditions.
This will happen easily, and the aldehydes will form a carboxylic acid that has the same number of carbon atoms.
HCHO + [O] → HCOOH
CH3CHO + [O] → CH3COOH
The carboxylic acids are the most common organic acids.
