Which sentence correctly uses dashes for punctuation?

Responses
A My—brothers Ron and Jack—are visiting us next week.My—brothers Ron and Jack—are visiting us next week.
B My brothers—Ron and Jack are visiting—us next week.My brothers—Ron and Jack are visiting—us next week.
C My brothers Ron and Jack—are visiting—us next week.My brothers Ron and Jack—are visiting—us next week.
D My brothers—Ron and Jack—are visiting us next week.

D My brothers—Ron and Jack—are visiting us next week.

In this sentence, the dashes are used correctly to set off the non-essential information "Ron and Jack," which is an appositive providing additional detail about "my brothers." The sentence without the appositive would still make sense: "My brothers are visiting us next week." Therefore, option D is the correct use of dashes for punctuation.
