Answer:
O A. I have some . . . fantastic news to share.
Step-by-step explanation:
Punctuation allows for a better understanding and usage of the English language in such a way that there are indications for how the sentences must be taken and how they are to be read. It also shows when and where the sentence ends, pause or even have a long pause, as in hesitation.
In the given sentences, the best show of hesitant speech is in the use of (. . .) in the sentence. This indicates that there is some sort of pause in the sentence, before "fantastic". Options C and D have no pause so they are wrong. Option B uses a hyphen, which is not how pauses are indicated.
Thus, the correct answer is option A.
