The answer is B) or the second option ''The history professor asked, ''What famous event happened on April 4, 1968 in Memphis, Tennessee?'' because the first option has way too many commas used for a date and place but the second option has the perfect amount needed so therefore its B).'
Whenever a date is placed in the middle of a sentence the correct way to punctuate it is by placing a comma before and after the year. The sentence that is correctly punctuated is sentence 1 because it follows this rule; there is a comma before and after 1968 that separates the date from the rest of the sentence.
