A Correct answer
Explanation

'Useful' begins with a consonant sound /j/ (as in 'you'), not a vowel sound, so the correct article is 'a.' Articles are determined by the spoken sound that follows, not the written letter. Even though 'useful' starts with 'u,' it takes 'a' because the /j/ sound is consonantal.
