Concept:The underlined vowel sound is the long open-mid back vowel /ɔː/.Explanation:The word "brought" is pronounced /brɔːt/, so it contains the vowel sound /ɔː/.The word "bowl" is pronounced with /əʊ/, not /ɔː/.The word "loan" also has the /əʊ/ sound.The word "laugh" has a different vowel sound, not /ɔː/.So the word with the same vowel sound as the underlined letters is "brought".Answer:A. brought
