Concept:Identify the word whose pronunciation contains the phonetic sound shown in the question.
Explanation:The word "comfort" has the phonetic transcription /ˈkʌm.fət/.
This transcription includes the exact vowel sound indicated by the given phonetic symbol.
In phonetic questions, always read the transcription carefully, because the stressed syllable often contains the target sound.
For "comfort", the first syllable /kʌm/ carries the vowel sound that we need.
Now check the other options: "music" is pronounced /ˈmjuː.zɪk/, "ozone" is pronounced /ˈəʊ.zəʊn/, and "food" is pronounced /fuːd/.
None of these words has the same vowel sound as the one represented by the phonetic symbol.
Therefore, among the words lettered A to D, the correct choice is "comfort".
Answer:A. comfort
