Best Answer Explained in Below-:

The correct answer is "A) an." This choice is appropriate because "Oxford" begins with a vowel sound, which typically requires the indefinite article "an" instead of "a." The phrase you're completing, "Oxford is ______ English university," introduces a singular noun phrase. When referring to a nonspecific example of a thing or concept—in this case, a university—we use the indefinite article to indicate that it could be any one of a number of similar entities.

In English, "an" is used before words that start with a vowel sound (a, e, i, o, u) to facilitate smoother pronunciation. Despite starting with the letter "E" in "English," which might initially mislead one into thinking "a" would suffice, the key here is the vowel sound that "English" produces. Therefore, we say "an English university."

Thus, the complete sentence reads: "Oxford is an English university," correctly presenting Oxford as one among many English universities, emphasizing its general status rather than a specific distinction.
