Topic: Article,

Best Answer Explained in Below-:

The correct answer is C) "An university" because it demonstrates an incorrect application of the article "an." In English, the choice between "a" and "an" depends on the sound that begins the following word, not strictly on its initial letter. The article "an" is used before words that begin with a vowel sound, while "a" is used before words that start with a consonant sound.

In the case of "university," although it begins with the vowel letter 'u,' it is pronounced with a 'yoo' sound (a consonant sound) at the beginning. Therefore, the correct article to use is "a," making the correct phrase "a university."

In contrast, the other options use articles correctly. "An hour" is correct because "hour" starts with a vowel sound (the 'o' in “hour” is pronounced). "The earth" uses "the," which is the definite article and is appropriate for a unique noun. "Men" does not require an article in this context when speaking in general terms. Thus, "an university" is the only option where the article usage is incorrect.
