Which word features the long vowel /O/ sound?

The word that features the long vowel /O/ sound is "Boat." In this word, the 'oa' part represents the long /O/ sound, pronounced like "oh." Recognizing long vowel sounds is crucial in phonics, as it helps with decoding and spelling words accurately. The other options contain different vowel sounds; for example, "Boot" features a long /U/ sound, while "Bound" has an /A/ sound that is not long and "Brown" includes a diphthong that combines vowel sounds, which does not reflect the isolated long /O/ sound. Thus, "Boat" stands out for its clear representation of the long vowel sound being studied.
