The correct answer here would be the third option.
The order of importance would be the best strategy here in my opinion because you would want to stress the most important notion first, which is the part that would be most discussed. The less important details (they are still important though) you would discuss later as in order not to take the focus of the most important thing.
The more populated districts
Alright, so, let's see:
Problem Solution: Gives a problem, suggests a solution
Chronological Order: Lists events by the order they happened in time.
List form: Don't worry about this.
Comparison and Contrast: Finding similarities and differences between two said topics
Now, I can say with confidence that All are wrong except Chronological Order. Why? There are no problems to solve, it's just telling you what happened. There also aren't two things to compare similarities and differences with. List form is automatically out.
I know it's Chronological order because it says: "In 1798, Napoleon went to Egypt to protect its trade interests." Then, it says: "<span>The following year, the French bolstered their defenses by rebuilding a fort in the town of Rosetta" It is going by order of date, thus Chronological Order.
Your answer is Chronological Order.
