Question

Fill in the blank with an appropriate article:

That's his house. I had my camera with me and took _____ photograph.

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

Answer 1

Answer: (B)

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.
   

We use an indefinite article in front of a singular countable noun. Hence option C is incorrect. Option A is incorrect as An can't be used with a word beginning with consonant. Henceforth option B is correct.
