The correct answer is letters—words—phrases—sentences.

Explanation:

The alphabetic method (also known as the spelling method) is a traditional synthetic method used in teaching reading. It follows a bottom-up structure progressing from the smallest visual and sound units of language to larger linguistic structures.

The standard procedural sequence of the alphabetic method is as follows:

1. Letters: Students first learn to recognize, identify, and name individual letters of the alphabet (e.g., A, B, C).

2. Words: Letters are combined together to spell and form words (e.g., c-a-t → cat).

3. Phrases: Words are combined into meaningful small groupings or phrases without complete predicate structures.

4. Sentences: Phrases are joined together to form complete grammatical sentences.

Hence, the correct progression is: letters → words → phrases → sentences.
