Simple! In order to put history in order, put the date the event took place! Or rather, the year, if no exact date. So, you would have to put them According to when it took place, or C!
According to when it took place, chronological order basically means by what time it happened, first, second, third, and so on..
So the answer would be C.
Hope that this helps you..
