Which word list progresses from simple to complex closed syllable concepts in early phonics instruction?

The word list that progresses from simple to complex closed syllable concepts in early phonics instruction is the one that includes "bit, wax, shop, left, bricks, cliff, planted." This selection contains an array of closed syllable words, starting with one-syllable words such as "bit" and "wax," which feature a single vowel followed by one or more consonants, effectively demonstrating the closed syllable pattern.

As the list progresses, it incorporates more complex forms with multiple syllables and varying consonant clusters, such as "bricks," "cliff," and "planted." This allows learners to encounter increasingly challenging phonetic structures while still adhering to the closed syllable pattern.

The other word lists contain examples that either remain at a simpler level without progression or deviate from the closed syllable focus. For instance, the first list focuses primarily on very basic, one-syllable words, while the third list includes vowel-diphthong words and the last list consists of long vowel sounds, which are not closed syllables. This makes the selected answer the most suitable choice for illustrating the concept of progressive complexity in closed syllable instruction.
