Answer
To determine the correct homologous series, we analyze the molecular formula C({6})H({12})O(_2). This formula indicates the presence of a hydroxyl group (-OH) characteristic of alcohols, and also a carboxyl group (-COOH), which is a hallmark of carboxylic acids. Given that there are more than one oxygen atom, it suggests that the compound can be classified under carboxylic acids.
