Concept:Compare the target consonant sound from the bracketed letters with the consonant sounds in all the options.
Explanation:The word "giggle" is pronounced /ˈɡɪɡ.əl/. The bracketed letters in it stand for the voiced velar plosive /ɡ/.
Option A: "league" is pronounced /liːɡ/. It ends with the same /ɡ/ sound.
Option B: "ensign" does not have /ɡ/; its "g" is silent.
Option C: "genre" has the consonant /ʒ/ instead of /ɡ/.
Option D: "gesture" has the consonant /dʒ/ at the start, not /ɡ/.
Since only "league" has the same consonant sound as the bracketed letters, it is the correct choice.
Answer:A. league
