Which letter is sometimes considered a vowel?

• A. A
• B. O
• C. U
• D. Y

Answer: (D)

Y is the letter that can function as both a consonant and a vowel. It carries a vowel sound and can form a syllable in words where there isn’t another vowel letter, as in rhythm or gym. At other times, it acts as a consonant, starting words with the /j/ sound, like yellow. The other letters listed are standard vowels that always serve as vowels in typical spelling, so they don’t fit the “sometimes a vowel” idea. That dual role is why Y is the correct answer.
