How many people had to evacuate their homes due to the 2004 Indian Ocean Tsunami?

The chosen answer is significant because it accurately reflects the scale of displacement caused by the 2004 Indian Ocean Tsunami, which was one of the deadliest natural disasters in recorded history. The immense power of the tsunami led to catastrophic impacts across multiple countries bordering the Indian Ocean, including Indonesia, Sri Lanka, India, and Thailand, among others.

The figure of 1 million people evacuated represents a broad estimate of those directly affected in terms of evacuations due to the disaster, as many communities were entirely devastated. While the exact number can vary in different reports, the high figure reflects the extensive damage and the chaos that ensued in the aftermath of the tsunami. It emphasizes the scale of the humanitarian crisis and the global response required for rescue and relief in the affected areas.

The other options suggest numbers that either underestimate or overestimate the displacement caused by this disaster, which could lead to misconceptions about the magnitude of the evacuation and the response efforts needed for recovery following such an unprecedented catastrophe.
