I believe the correct answer is B. It is the only sentence where the punctuation marks are correctly placed. For the first sentence, the apostrophe in Dorris should be placed in the last letter of the name and an s is not to be added since the name ends with an s. For option C, some commas should be inserted in the sentence to make sense of the sentence. And, for the last option, the semi colon is not to be used instead a period should be placed.
