Question

Fill in the blank with the most appropriate word.
She works as ______ clerk in a very large bank.

• A. a
• B. an
• C. the
• D. no article

Answer 1

The correct option is A a

1. An/A' is used as an indefinite article for a thing or person when the reader doesn't know which one we are referring to out of many nouns. It states the random nature of the subject.
2. 'The' is used as a definite article for a thing or person when the reader knows which one we are exactly referring to. It states the specific nature of the subject.
   

Option A is correct as 'A clerk' sounds logical and is grammatically correct. It means she is a clerk that is she belongs to a profession which goes with the meaning of the sentence. Moreover, A is used with singular countable noun. Option C is incorrect as 'The' is used with words which have been mentioned previously. The readers are unaware of her as clerk. Option B is incorrect because 'An' is used with a word having a vowel sound for a single countable noun which is random in nature. Option D is incorrect as an article is required in the blank to give meaning to the sentence.
