Which sentence is punctuated correctly? tanna president of the national honor society truly enjoys volunteer work. the old house, that my father grew up in, is being completely renovated. my sister, who is a waitress at billy’s big burger shack, is sixteen years old. the bird that built a nest in the oak tree, appears to have an injured wing.

The sentence that is punctuated correctly is "My sister, who is a waitress at Billy’s Big Burger Shack, is sixteen years old".

Explanation: "My sister, who is a waitress at Billy’s Big Burger Shack, is sixteen years old" is correctly punctuated because it separates the non-defining relative clause ("who is a waitress at Billy's Burger Shack"), which gives non-essential information about the antecedent ("sister"), from the rest of the elements of the sentence with commas. In contrast, the first sentence has not been punctuated in a correct way because the appositive phrase ("president of the National Honor Society") should be separated from the rest of the sentence with commas. Moreover, the second sentence is also incorrect because the relative phrase "that my father grew up in" cannot be written between commas. Finally, the last sentence has also been punctuated in an incorrect way since no comma should be placed before "appears".
