Question

Fill in the blank with the most appropriate word.
Helen has ____ headache.

• A. a
• B. the
• C. some
• D. an

Answer 1

The correct option is A a

In the given sentence, 'headache' is not a definite thing and so, the answer must also be indefinite. Also, 'headache' is a singular object and thus, the answer must be a word used for singular objects.

Option A is incorrect. 'a' is an indefinite article used with indefinite objects. Also, it can only be used with singular objects. Thus, it meets the required conditions and is the correct answer.

Option B is incorrect. 'the' is a definite article and cannot be used with indefinite objects. Thus, it is incorrect.

Option C is incorrect. 'some' can be used for indefinite objects but, it can only be used for plural objects and so, it is incorrect.

Option D is incorrect. 'an' is an indefinite article that can be used for indefinite and singular objects but, it can only be used if the word after it starts with a vowel. Since, headache does not start with a vowel, 'an' cannot be used.
