The correct answer is option 1: Primary alcohol.

When an alcohol undergoes oxidation, it can form different products depending on the conditions. In the given question, we are told that the alcohol first forms an aldehyde upon oxidation. This implies that the alcohol is a primary alcohol.

Primary alcohols have the general formula R-CH2-OH, where R represents a carbon chain or group attached to the functional group. In the oxidation process, the primary alcohol is converted into an aldehyde, which has the functional group R-CHO. Aldehydes have one carbon atom attached to the carbonyl group.

Upon further oxidation, the aldehyde can be converted into a carboxylic acid. Carboxylic acids have the functional group R-COOH, with one carbon atom attached to the carbonyl group and the other carbon atom attached to an alcohol group.

Therefore, since the alcohol in question forms an aldehyde and then a carboxylic acid, both with the same number of carbon atoms as the alcohol, we can conclude that the alcohol is a primary alcohol.
