Final answer:
Option C: The student can identify the beginning sound of single-syllable words.
Step-by-step explanation:
The informal assessment result that provides the clearest indication that a kindergarten child has attained a beginning level of phonemic awareness is option C: The student can identify the beginning sound of single-syllable words.
This is because phonemic awareness refers to the ability to hear, identify, and manipulate individual sounds (or phonemes) in spoken words. Being able to identify the beginning sound of single-syllable words demonstrates an understanding of the individual sounds that make up words.
For example, if a kindergartner can correctly identify that the word 'dog' starts with the /d/ sound, they are demonstrating phonemic awareness.
