Answer:
(D) Substitution and omission
Step-by-step explanation:
There are 4 kinds of mistakes in articulation commonly displayed in children. These are commonly known as Substitution, Omission, Distortion and Addition.
- SUBSTITUTION: Takes place when kids replace a sound they cannot produce for another that is already included in their speech. In this case, it is "wan" for "ran".
- OMISSION: Is evident when a sound is avoided because it is too hard to articulate. In this case, it is "hur" for "hurt".
- DISTORTION: happens when the sound is neither eliminated not replaced but does not sound properly. The kid then tries to produce the sound but it is wrongly articulated.
- ADDITION: Is, literally, the addition of a sound when it was not originally in the word.
