D)Nasal emission
E)Normal resonance

The nasal cul-de-sac test is used to diagnose hypernasality, which is when there is too much airflow through the nose during speech. If there is a difference in sound production when the cul-de-sacs are closed off, it confirms that the speech is being affected by excessive airflow through the nose. Hyponasality, on the other hand, is when there is not enough airflow through the nasal cavity during speech, and would not necessarily be detected by the nasal cul-de-sac test. Cul-de-sac resonance refers to sound that is trapped in the nasal cavity due to an obstruction or blockage, and nasal emission is the escape of air through the nasal cavity during speech. Normal resonance would not produce a difference in sound during the nasal cul-de-sac test.
