Select the most appropriate option to fill in blank no. 2.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. an.
- The complete sentence reads: "It is an area of nearly 2.8 million square miles."
- "An" is appropriate here because it is used before a word begins with a vowel sound. "Area" starts with a vowel sound, so "an" is the correct indefinite article. This choice maintains grammatical correctness and ensures the sentence flows smoothly.
