Complete the sentence: Varanasi is ______________________.

The English language is distinguished by three articles, and they can be classified into definite and indefinite articles. While “the” is regarded as the definite article, “a” and “an” are considered indefinite articles. “The” is used in instances when we talk of a particular place, person, or thing and when we mention a singular noun to represent the whole class(Eg. The tongue tastes). “A” usually precedes a consonant(A ball, A pharmacy) or a vowel with a consonant sound(Eg. A yak, A university), and “an” is usually succeeded by a word that begins with a vowel(Eg. An astronaut) or a silent “h”(Eg. An hour).
So, the correct way to frame the sentence is, “Varanasi is a holy city.”
