The Solution I recommend ! !

I would recommend the third option. I recommend this because, my idea is that once everyone herd of the cyclone warning they can go to Dhaka and be safe. Even though all the other places will be distroyed, at least the country won't have to start all over again, because the country basically runs on Dhaka. Another thing is that everyone survive.

Cyclones and Flooding in the Brahmaputra Delta

40 years ago, a storm formed over the Bay of Bengal on November 8, 1970, and reached a maximum sustained wind speed of 115 mph (185 kph) before making landfall on November 12. Unfortunately it hit a very densely population of Bangladesh, killing several hundred thousand people and ranking, according to the NOAA in 2008, as the third deadliest natural disaster in history. Another cyclone happened in 1991, but their is yet to come. Cyclones like this can suck people out to sea and kill them, but also distroy all their houses and belongings.
