Correct option is C
The /n/ sound in "noise" is classified as a nasal consonant based on articulation. Nasal sounds are produced by allowing the airflow to pass through the nose while the mouth is closed at a specific point of articulation. In the case of /n/, the tongue touches the alveolar ridge (just behind the upper front teeth), making it an alveolar nasal sound.
Information Booster:
• Nasal sounds in English include /n/, /m/, and /ŋ/.
• The airflow is blocked in the oral cavity but escapes through the nasal cavity.
• The /n/ sound is voiced, meaning the vocal cords vibrate during its production.
• Alveolar sounds are articulated with the tongue against the alveolar ridge.
• Nasals contribute to the resonant quality of speech.
Additional Knowledge:
• Plosive: Involves a complete blockage of airflow, followed by a release, such as /p/ and /t/.
• Affricate: Combines a plosive and a fricative, like /tʃ/ in "chair."
• Lateral: Refers to sounds where the airflow passes along the sides of the tongue, as in /l/.
