Which of these would most likely impact the economic development of southeast asia? a) avalanches b) drought c) tornadoes d) typhoons

The most probable answer to this question would be D. Typhoons.

Avalanches are close from little to none in occurrence in the south-east Asian Nations since most of the places located there don't have the season of winter or phenomenons that might result to snowing. Tornadoes are also close from little to none since these don't usually spawn in the lands of the south-east Asian nations. Drought would be a plausible answer to this question, but the occurrences if it happening were only second to typhoons. Typhoons, on the other hand, occur every year and sometimes occurs almost throughout a year. This is due to the nations of the south-east Asia being located near the Pacific and lies under the Typhoon Belt.
