(D) Substitution and omission

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.
