Question

Fill in the blank with the correct option : 
Mr. Sudhir Soni is _____ R. A. S. Officer.

Accepted Answer

Mr. Sudhir Soni is **an** R. A. S. Officer.

**Explanation:**

*   **Why Option 1 (an) is correct:** The article "an" is used before words that begin with a vowel *sound*. While "R. A. S." starts with the letter 'R', it is pronounced as "Ar-A-S". The initial sound is a vowel sound ("A"). Therefore, "an" is the correct article to use in this case.

*   **Why Option 2 (a) is incorrect:** The article "a" is used before words that begin with a consonant sound. Since "R. A. S." begins with a vowel sound, "a" is grammatically incorrect.

*   **Why Option 3 (the) is incorrect:** The article "the" is used to refer to a specific or definite noun. In this sentence, we are introducing Mr. Sudhir Soni as *one of* the R. A. S. Officers, not a specific, already identified one. Therefore, "the" is not appropriate.

*   **Why Option 4 (× - no article) is incorrect:** An article (a, an, or the) is generally required before a singular noun that identifies a profession or role. Since "R. A. S. Officer" is identifying Mr. Sudhir Soni's role, omitting the article would be grammatically incorrect.
