Q:

Which sentence is punctuated correctly?

A) One question you should always ask yourself: “Am I pleased with the results?” B) Always ask yourself this question: “Am I pleased with the results?
C) Always ask yourself a question like: “Am I pleased with the results?” D) One question you should always ask yourself is: “Am I pleased with the results?”
 
Answer & Explanation Answer: A) One question you should always ask yourself: “Am I pleased with the results?”

Explanation:

The second would employ a comma, or semi-colon, and not a colon so it is not properly punctuated.

 

The third sentence would not be correct because it uses 'like', usually used for comparison. Since you are not comparing two questions, it would not be appropriate.

 

The fourth sentence has 'is' before the colon, which is a implies declaration and not listing. So, again, it would not be appropriate.

 

Hence, the first sentence, however, is punctuated correctly.
