The ellipsis is a set of three periods used to indicate an omission. Each period should have a single space between each other, save in the event of a quotation mark.
One of their uses in informal writing is to indicate hesitation. This would be the case of these examples. The sentence that correctly uses an ellipsis in this case would be A. This is so because the hesitation that the speaker or writer is trying to evoke has to do with the consequences of not cooperating with the police.
