Question

Fill in the blank with the most appropriate word.
Butterflies are ______ insects.

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

Answer 1

Answer: (D)

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 D is correct as no article is required to carry out the meaning of the sentence. Option A is incorrect as 'A' as an article doesn't suit the blank as 'a insects' is wrong. Option B is incorrect as 'an insects' is incorrect. 'An' is used with a word having a vowel sound. 'An insect' is grammatically correct. Option C is incorrect as 'The' doesn't suit the meaning of the sentence.
