Answer:
Hi!
The answer to your question would be option D. The history professor asked, open double quote “What famous event happened on April 4, 1968, in Memphis, Tennessee? close double quote. ”
Explanation:
The reason why this is the correct answer is because of the following:
1- There needs to be a coma after the word asked to denote a pause between what the professor asked and the opened double quote. This eliminates option B.
2- There needs to be a coma between Memphis and Tennessee to denote that Memphis belongs as a city to Tennessee, the state. This rules out option A.
3- There doesn't need to be a pause between the words happened and on April 4 because a pause is not needed and a pause would only cut the sentences making them not able to stand on their own. This rules out option C and we are left with option D as the answer.
