Which example demonstrates a phonetic pattern of vowel teams?

The correct choice demonstrates a phonetic pattern of vowel teams, which refers to two vowels working together to produce a single vowel sound. In the word "pea," the "ea" forms a vowel team that creates the long "e" sound. This showcases how specific combinations of vowels can alter pronunciation and spelling patterns in English.

Other choices, while they contain vowels, do not illustrate this specific phonetic pattern. For instance, "fan" features a single vowel followed by a consonant, "home" contains a silent 'e' that changes the preceding vowel sound but does not include a vowel team, and "chicken" contains a short vowel sound again not reflecting the concept of vowel teams. Thus, "pea" is the best example of a word that highlights the phonetic pattern of vowel teams.
