Choose the sentence that contains an error.

Correct option is A

Option (a) contains an error.
Explanation:
The article “an” is used before vowel sounds, not just vowel letters. “New” starts with a consonant sound /n/, so the correct article is a, not an.
Correct I need to buy a new iPhone.
Grammatical rule used:
�� Use ‘a’ before consonant sounds and ‘an’ before vowel sounds.
Example:
· An hour (because ‘hour’ starts with a vowel sound /auər/)
· A university (because ‘university’ starts with a ‘yoo’ sound)
