Identify the sentence that is correctly punctuated.

B. It is not always necessary, however; to check the entire set of books.

C. It is not always necessary, however, to check the entire set of books.

D. It is not always necessary however, to check the entire set of books.

A

Nope.

Right.

The correct sentence that is correctly punctuated is option C. "It is not always necessary, however, to check the entire set of books." In this sentence, there is a comma after the introductory phrase "It is not always necessary" and another comma before and after the word "however." This follows the correct punctuation rules for using a comma to set off an introductory phrase and to indicate a pause when "however" is used as a transition word.
