Question

Fill in the blank with the most appropriate option:
This is ______________________.

• A. the question thirty
• B. the question thirteenth
• C. question thirty
• D. thirteen question

Answer 1

The correct option is C question thirty

Option C: This is the most suitable option, because the noun 'question' does not require an article here.

We do not use an article when the form is noun + number. Since the form in the given sentence is 'question (noun) + thirty (number), this option is correct.

Option A: This option is incorrect for the same reason mentioned above, as the article 'the' isn't used when the form is 'noun + number'.

Option B: The word 'thirteenth' is an adjective of number. We should use it before the noun 'question': the thirteenth question, and not after. Hence B is incorrect.

Option D: The word 'thirteen' is an adjective of number. It modifies the noun 'question' as a plural noun. Since it's plural, the correct form should be 'questions'. Also, the verb in the given sentence is singular 'is'. (The verb must agree with the noun in terms of number.) Hence this option is incorrect.
