Concept:The symbol /iə/ represents a diphthong sound heard in words like “ear” and “peer.”Explanation:The word “pair” is pronounced /peə/, which contains the /eə/ sound, not /iə/.The word “lure” is pronounced /lʊə/ or /ljʊə/, so it does not contain /iə/.The word “lower” is pronounced /ləʊə/, which does not match /iə/.The word “peer” is pronounced /pɪə/, and it clearly contains the /iə/ sound.Therefore, the correct option is “peer.”Answer:D. peer
