Answer:
C) "Your friend," she said, "is waiting for you."
Explanation:
Punctuation is the use of certain signs and writing forms to make a sentence correct and presentable. And in punctuation, it includes the use of commas, or any punctuation marks and capitalization in a sentence, to make it right.
Among the given sentences, the correct punctuated sentence is option C. This is because the sentence given in the direct speech requires the use of inverted commas to signify the speech. At the same time, the comma after 'friend' denotes that the speech is continuing. And the insertion of 'she said' in between the full direct speech requires the quoted speech to be on pause and not stopped with a period (.).
Thus, the correct answer is option C.
