Final answer:
Option (c), The nasal phoneme in the word 'anger' is /ŋ/, which is articulated by the back of the tongue against the soft palate, and is the same sound found in 'singer' or 'ringing'.
Step-by-step explanation:
The nasal phoneme you hear in the word "anger" is /ŋ/. This is the same sound you find in the middle of words like 'singer' or 'ringing'. This sound is not the /m/ you hear in 'map', the /n/ in 'nap', nor the /ɳ/ which is a retroflex nasal sound not commonly used in English.
In "anger", the /ŋ/ sound is articulated by the back of the tongue against the soft palate or velum, similar to the position for the sound [g], which you hear at both the beginning and end of 'gag'. The phoneme /ŋ/ is distinct in that it is a nasal sound, meaning air is allowed to escape through the nose during its articulation.
