Choose the correct option for the blanks in the sentence:

Aditi is really happy today as her brother has become _____ NCC cadet.

An

The correct answer is Option (2) → An

The indefinite article "an" is used before singular nouns that begin with a vowel sound. The word "NCC" begins with a vowel sound, so the correct answer is "an NCC cadet."

Other options:

B. NCC cadet: The definite article "the" is used before singular nouns that are specific or unique. The sentence does not specify which NCC cadet Aditi's brother is, so the definite article is not correct.

C. a N.C.C. cadet: The abbreviations "NCC" and "N.C.C." are both correct, but the period after the "C" in the second abbreviation is not necessary.

D. Zero or No article: An article is not used before singular nouns that are uncountable or that begin with a consonant sound. The word "NCC" is not uncountable, and it does not begin with a consonant sound, so an article is necessary.
