D. All of the above.

Answer 1

The Indus Valley Civilization declined due to environmental factors, invasion by outside forces, and economic decline.

Step-by-step explanation:

The decline of the Indus Valley Civilization is believed to have been caused by a combination of factors:

1. Environmental factors: Environmental degradation due to resource exploitation, high population density, climate change, and disease likely played a role in the civilization's decline.
2. Invasion by outside forces: The civilization was vulnerable to attacks by raiding groups like the Aryans, who likely took advantage of the weakened state of the region.
3. Economic decline: Centuries of urbanization and population growth may have led to environmental degradation, making the land unsuitable for sustaining human populations.
