The correct answer is chrono, because if it were relating to time you would want it in Chronological Order. Chronological order is to do with time and how events happen through time, if a series of robberies happened, it would be recorded by police in chronological order, this means they recorded the dates and times of the robberies and organized them to where the most recent robbery is the newest in the order, and the first robbery is the first account of all the robberies.
Example:
Robberies happened 2011 through 2013
It is 2011 through 2013 because the first robbery happened in 2011 and the robberies ended in 2013.
This is Chronological order.
