Best answer
The correct option is (b) Thiols

The explanation: Thiols does not impart flavour to the beer. Some aromatic alcohols, esters, carbonyls, and various sulphur-containing compounds are yeast metabolites that contribute to beer flavour. They are chemically diverse and includes organic acids and medium chain-length aliphatic alcohols.
