Choose the correct article in the following sentence– “He is …….. one-eyed man

The answer is A. Articles follow sound, not spelling. “One” begins with the consonant sound /w/, so the indefinite article must be “a”, giving “a one-eyed man”.

• B is wrong. “An” comes before a vowel sound, and “one” is not pronounced “on”. The vowel letter misleads people here.
• C is wrong. “The one-eyed man” points to a specific man already identified. The sentence places him in a category (one-eyed men), so the indefinite article fits.
• D is wrong because option A is correct.

Core concept: the indefinite article (a/an) versus the definite article (the), and the rule that the choice depends on the initial sound. This is basic usage, but it matters in Prelims English-usage questions and in Mains answers where precision of expression is rewarded.

Trap: students see the vowel letter “o” in “one” and pick “an”. Check the first sound, not the first letter.
