Question

The question is not whether Serena Williams will win a twenty-third Grand Slam title, but when.
Choose the option that best corrects the underlined words.

• A. NO CHANGE
• B. but when,
• C. but when?
• D. but when!

Answer 1

The correct option is A NO CHANGE

According to general rule, a question mark is used at the end of a direct sentence whereas, indirect sentences are ended with a period.

The given sentence is an indirect sentence, thus a period should be used to end the sentence.

Thus, the correct answer will be Option A, no change.

Option B and D are incorrect, because a comma is never used at the end of a sentence and an exclamation mark is used to express strong feelings, high volume or for emphasis.
