Out of the following sentences, the one that uses dashes correctly is - "The New Zealand Papua New Guinea handball team's stars Fredrickson, lacho, Honey, and Ipatas, have all demonstrated - hey, what's that duck doing here? Here, the right answer is Option B.
<u>Explanation</u>:
There is a surprise element at the end of the sentence which is marked by an exclamation ‘hey’ and a question. So, the dash is placed after the verb ‘demonstrated’ to highlight this surprise element of the sentence.
