Answer:
D. Renaissance
Step-by-step explanation:
Okay, we can automatically rule out the Cold War because that was in a completely different era with Russians and whatnot. We can also rule out the Industrial Revolution because that was also in a different time period. Now, the Protestant Reformation was about people leaving the Catholic Church, and it was during that time period, but it wasn't about Greek and Roman literature and stuff, so that leaves us with the Renaissance. The Renaissance was the time period of artists like Leonardo da Vinci, and scientists like Issac Newton (I think, don't quote me on that), and enlightenment thinkers like John Locke, so I think that the Renaissance is the best answer
