Question

Which sentence is punctuated correctly?

Answer 1

Of the following choices given, B. My Sister asked me, "So, where do you think we should go first"?, is the sentence that's punctuated correctly. Notice that the sentence clearly implies its meaning and is understandable because the punctuation marks are correctly in place. 

Answer 2

The sentence that is punctuated correctly is D) "Absolutely," insisted the guide, "especially if you want to get back before the tour bus leaves!"
The other sentences either don't have punctuation marks where they need them, or they put quotation marks in the wrong places.
