The correct answer is option 2 - Thailand. This means that Thailand suggested the name `Amphan` to the cyclone that caused significant damage in West Bengal and Bangladesh in May 2020.
Option 1 - Bangladesh is incorrect. Bangladesh was one of the countries affected by the cyclone, but it did not suggest the name.
Option 3 - Maldives is incorrect. The Maldives is not associated with suggesting the name `Amphan` to the cyclone.
Option 4 - India is incorrect. While India was also severely impacted by the cyclone, it did not suggest the name `Amphan`.
The naming of tropical cyclones is done by regional meteorological centers, and each name is contributed by a different country in the region. In this case, Thailand suggested the name `Amphan` for this cyclone. It is important to note that this naming process helps in easily identifying and tracking cyclones, and it is not related to the country where the cyclone originated from or had the most impact.
