[amp_mcq option1=”a” option2=”an” option3=”the” option4=”none of these” correct=”option1″]
The correct answer is: A. a
The word “hour” is a countable noun, so it takes an indefinite article “a” or “an”.
- “A” is used before singular nouns that start with a consonant sound.
- “An” is used before singular nouns that start with a vowel sound.
In this case, the word “hour” starts with a consonant sound, so we use the indefinite article “a”.
The other options are incorrect because they are definite articles. A definite article is used to refer to a specific person, place, thing, or idea. In this case, we do not know when Karan will arrive, so we cannot use a definite article.
