Why The Indus Ganges and Brahmaputra are all .?

The Indus, Ganges, and Brahmaputra are major river systems in South Asia that originate from the Himalayas and flow through diverse landscapes before emptying into the sea. They play a crucial role in the region's agriculture, providing water for irrigation and supporting millions of people. Additionally, these rivers hold significant cultural and religious importance, particularly in Hinduism, where they are often revered as sacred.
