Concept:The phonetic symbol /ŋ/ represents the voiced velar nasal sound, commonly produced when pronouncing the letters “ng” in English.
Explanation:Listen to the sound in the middle of each option word.
In “reign”, the ending is pronounced as /n/, not /ŋ/.
In “sink”, the “n” is pronounced as /ŋ/ before the /k/ sound.
Thus, “sink” gives the required sound /ŋ/.
The words “hinge” and “thin” use the sounds /ndʒ/ and /n/ respectively, so they do not match.
Answer:B. sink
