Step 1: Read the sentence
The sentence is: “He is _____ honourable man.” The blank requires the correct article. Options: (a) a, (b) an, (c) the, (d) none.
Step 2: Rule of article usage
- "a" is used before singular countable nouns starting with a consonant sound.
- "an" is used before singular countable nouns starting with a vowel sound.
- "the" is used when referring to something specific or unique.
- "none" means no article is required.
Step 3: Focus on pronunciation of “honourable”
Although “honourable” begins with the letter "h," the "h" is silent in pronunciation. The word is pronounced as if it begins with a vowel sound: "onourable." Because article choice depends on sound, not spelling, we must use "an," not "a."
Step 4: Correct sentence
“He is an honourable man.” This is the grammatically correct form.
Final Answer: The correct option is (B) an.
