Final answer:
The false statement about phonation is C. "It is produced when a person says 'sh'", as this sound does not involve the vibration of the vocal folds which is a requirement for phonation.
Step-by-step explanation:
Phonation is the process involved in producing vocal sounds. The statement about phonation that is FALSE is C. It is produced when a person says "sh". This is because the "sh" sound is an example of a voiceless consonant sound, where the vocal folds do not vibrate. Phonation involves the vibration of the vocal folds and requires respiration to provide the airflow needed to make the vocal folds vibrate. When we produce sounds like "wvvv", we are using our vocal folds to create that vibration; hence, statement A is true. Statement B is true as it correctly describes the product of vibrating vocal folds, which is fundamental to the concept of phonation. Lastly, statement D is true because respiration provides the necessary air pressure to initiate and continue phonation.
