Answer: The sentence that is punctuated correctly is the first one: "Give me liberty or give me death!" said Patrick Henry.
Step-by-step explanation: When citing another person's words directly, it is important to follow the punctuation rules that apply to direct quotations. For example, when the quotation includes an exclamation mark at the end, the comma that comes right before the second quotation mark must be omitted. For that reason, the first sentence ("Give me liberty or give me death!" said Patrick Henry) is the one that has been punctuated correctly. In contrast, the second and third sentences leave the exclamation point out of the quotation, while the fourth sentence does not even include the exclamation mark.
