Which of the following sites is known with first ever evidence of canal irrigation?

Correct option is B

The site known for the first ever evidence of canal irrigation in the context of the Indus Valley Civilization is Shortughai.

Canal Evidence: Traces of canals have been found at Shortughai, a Harappan site located in what is now northern Afghanistan.
Irrigation for Agriculture: These canals were likely used for irrigating fields, demonstrating the Harappans' agricultural practices and water management capabilities. This site is particularly well-documented for its clear evidence of an irrigation system.

Additional Knowledge

Dholavira: This site is known for its sophisticated water harvesting and management system, including massive reservoirs, dams, and channels for storing rainwater, but not for large-scale canal irrigation from a distant river.

Harappa and Mohenjodaro: While these major cities had advanced water management systems, including wells and intricate urban drainage, there is less distinct evidence of large irrigation canals in their immediate vicinities compared to Shortughai.
