Because only Indonesia is on the sea side and all countries and not on the seaside.

Most likely country to be affected by cyclones: Indonesia

Introduction:
Cyclones, also known as hurricanes or typhoons, are powerful storms that form over warm ocean waters. They are characterized by strong winds, heavy rainfall, and storm surges. While cyclones can form in various parts of the world, some regions are more prone to these natural disasters than others. Among the given options, Indonesia is the most likely country to be affected by cyclones.

Factors contributing to cyclone formation:
Several factors contribute to the formation and intensity of cyclones. These include:

1. Warm ocean waters: Cyclones form over warm ocean waters with surface temperatures above 26.5°C (80°F). Indonesia, located in the tropical zone, is surrounded by the warm waters of the Pacific and Indian Oceans, providing the ideal conditions for cyclone formation.

2. Geographic location: Indonesia is situated along the equator, which acts as a highway for tropical storms. This region is known as the "Ring of Fire" due to its high seismic and volcanic activity. The combination of warm ocean waters and its geographical location makes Indonesia highly susceptible to cyclones.

3. Monsoon winds: Indonesia experiences monsoon winds, which can contribute to the formation and intensification of cyclones. The convergence of winds during monsoon seasons creates favorable conditions for cyclone development.

Indonesia's vulnerability to cyclones:
Indonesia's geography and climate make it highly vulnerable to cyclones. Some key factors contributing to its vulnerability are:

1. Archipelago nation: Indonesia is an archipelago consisting of thousands of islands, making it highly exposed to cyclones. The large coastline and scattered islands increase the chances of cyclones making landfall in multiple areas.

2. High population density: Indonesia is the fourth most populous country in the world, with a significant portion of its population living in coastal areas. The high population density, combined with the vulnerability of coastal regions to cyclones, puts millions of people at risk.

3. Limited infrastructure and resources: Many parts of Indonesia, particularly remote islands, have limited infrastructure and resources. This hinders disaster preparedness and response efforts, making it challenging to mitigate the impacts of cyclones effectively.

Conclusion:
Given Indonesia's geographical location, warm ocean waters, and susceptibility to monsoon winds, it is the most likely country among the given options to be affected by cyclones. The archipelago nation's high population density and limited resources further increase its vulnerability to these natural disasters. It is crucial for Indonesia to invest in disaster management strategies, infrastructure development, and early warning systems to minimize the impacts of cyclones and protect its population.
