What is the best way to punctuate the bolded portion of the sentence? “i am sure beth said “that you are right.” “i am sure, beth said, “i am sure beth said, “i am sure” beth said “i am sure,” beth said,

The correct answer is “I am sure,” Beth said, "that you are right."

Explanation:

This is the correct option because, in American English, commas and periods always go inside the quotation marks. Moreover, the quoted text should be capitalized if we are quoting a complete sentence, and not capitalized if it is a fragment or if we are splitting the quote to interject a parenthetical like "that you are right."
