Answer:
The sentence that exhibits proper usage is:
D. Leonardo da Vinci's Mona Lisa is probably the most famous painting in the world.
Step-by-step explanation:
The reasons behind are the following. first A and C are the same exact answer. And they are wrong because they separate "Mona Lisa" with quotation marks that are not required. After all, we are talking direclty about it, we don't need to quote it because that is its name. Then B, separate three phrases to say we are not talking about the same idea. Therefore eventhough D is a long sentece it keeps the sense and the idea.
