Final answer:
The correct proofread sentence is option B, which contains the proper use of punctuation, capitalization, and quotation marks without any spelling errors.
Step-by-step explanation:
The correct sentence for proofreading is option B) On the Fourth of July, President Obama included an excerpt from the book "The Price of Freedom" in his speech. This sentence is properly punctuated with commas, uses capital letters appropriately for the date and title, includes necessary quotation marks around the book title, and maintains the proper form of the word 'from.' In contrast, the other options have various issues such as missing commas, incorrect capitalization, missing quotation marks, or misspellings.
