Morphology
This is a transparent adjective+noun composition: combining 'aromatic' (benzene-like ring structure and properties) with 'hydrocarbon' (a compound of hydrogen and carbon) yields the meaning 'a hydrocarbon that is aromatic/contains benzene rings' directly from the parts. Scientific noun phrases like this are compositional and cross-linguistically regular, so a learner who knows the constituent definitions will readily infer the MWE meaning. (If a learner only knows the everyday sense of 'aromatic' = 'having a smell', they might be confused, but the assessment assumes knowledge of the given constituent meanings.)
Etymology
The term aromatic hydrocarbon comes from early chemists who called some substances aromatic because they had a strong 'smell' and called molecules hydrocarbon because they were 'made of hydrogen and carbon'. Many of those smelly molecules were noticed first, so today aromatic hydrocarbon means a hydrocarbon with a ring shape, and the word 'aromatic' is a memory hint to its old link to 'smell'.
