Choose the nasal's sounds :

Question

Accepted Answer

Option 1, which includes the sounds | m, n, ŋ |, is the correct choice for nasal sounds. Here's why:

1. **Explanation for Option 1:**
   - Nasal sounds are produced when the airflow passes through the nose. This occurs because the velum (soft palate) is lowered, allowing air to escape through the nasal cavity.
   - The sounds | m, n, ŋ | are classic examples of nasal consonants:
     - **m**: This sound is produced with both lips (bilabial) and is voiced, allowing air to pass through the nose.
     - **n**: This sound is produced with the tongue against the alveolar ridge (alveolar) and is also voiced, with nasal airflow.
     - **ŋ**: This sound is produced with the back of the tongue against the soft palate (velar) and is voiced, with nasal airflow.

2. **Explanation for why other options are incorrect:**

- **Option 2: | l, p, t |**
     - These sounds are not nasal. 
     - **l** is a lateral consonant, where the airflow is directed over the sides of the tongue.
     - **p** and **t** are plosive sounds, where the airflow is stopped and then released, with no nasal passage involved.

- **Option 3: | w, j, z |**
     - These sounds are not nasal.
     - **w** and **j** are approximants, where the articulators come close together but do not create a turbulent airflow.
     - **z** is a voiced fricative, where the airflow is partially obstructed, creating a turbulent sound, but not through the nasal passage.

- **Option 4: | θ, ð, ∫ |**
     - These sounds are not nasal.
     - **θ** and **ð** are dental fricatives, produced with the tongue against the teeth, creating a turbulent airflow.
     - **∫** is a voiceless postalveolar fricative, where the airflow is directed over the tongue and through a narrow channel, creating turbulence, but not through the nasal passage.

In conclusion, Option 1 is the correct choice because it includes the nasal sounds | m, n, ŋ |, which are characterized by airflow through the nasal cavity, unlike the sounds in the other options.
