The correct answer is: A. a
The article “a” is used before singular nouns that refer to a general or unspecified thing. In this case, the village where Mr. Roy lives is not specified, so the article “a” is used.
The article “an” is used before singular nouns that begin with a vowel sound. In this case, the word “village” does not begin with a vowel sound, so the article “an” is not used.
The article “the” is used before singular nouns that refer to a specific or particular thing. In this case, the village where Mr. Roy lives is not specified, so the article “the” is not used.
The answer “none of the above” is incorrect because the article “a” is the correct article to use in this case.
