For the following reaction sequence, choose the correct option

Compound \(P\) gives a red-orange precipitate with 2,4-DNP reagent and does not reduce Fehling's reagent. On drastic oxidation with chromic acid, \(P\) gives an aromatic product \(Q\) which produces effervescence on treating with aqueous \(\ce{NaHCO3}\). Compounds \(P\) and \(Q\), respectively, are:

Identify the product in the following reaction:

Statement I: The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole - dipole interactions
Statement II: The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H-bonding.
In the light of the above statements choose the most appropriate answer from the options given below:
