Answer: The sentence that demonstrates the correct use of an elongated hyphen is A. On a hot summer day the little kids could only think of one way to cool off - popsicles.
Explanation: An elongated hyphen separates one word or phrase from the main body of a sentence mainly to add emphasis. However, it is highly important not to divide the main body of the sentence when using elongated hyphens. In that way, the correct answer is A. "On a hot summer day the little kids could only think of one way to cool off - popsicles" since the elongated hyphen has been used to detach only one word from the rest of the sentence. Moreover, this punctuation mark has been added to emphasize the word "popsicles". Furthermore, unlike what happens in B., C. and D., in sentence A. the elongated hyphen does not divide the main body of the sentence.
