Which writing sample suggests a developing understanding of the alphabetic principle?

The response indicating that KLD: "Casey loves Dancing" suggests a developing understanding of the alphabetic principle is well-founded. The alphabetic principle refers to the recognition that letters and letter patterns represent the sounds of spoken language. In the provided sample, the writer constructs a recognizable phrase with appropriate capitalization and spacing, indicating an understanding that letters are used to convey meaning.

The use of an abbreviation, KLD, followed by a coherent phrase demonstrates that the writer is beginning to connect sounds to letters and can formulate them into meaningful words. This suggests foundational knowledge of how letters function to create words in a structured way.

In contrast, the other options, while also indicative of some writing skills, do not align as closely with demonstrating the understanding of how individual letters or letter combinations correspond to the sounds in spoken language. For instance, "ABCDEF: 'Those are letters'" appears to be a random sequence of letters without identifying meaningful words, and "MIA: 'I write my name!'" shows a basic recognition of writing one's name but lacks the depth of understanding of phonetic representation in full sentences. "T Lo LE O: 'The dog went home'" includes several fragmented elements that appear disconnected from a coherent understanding of spelling patterns or sentence structure
