Which of the following is NOT a sustainable way of using water? A. Minimum amount of water for irrigation is used B. Rainfall water harvesting C. Planting crops with broad leaves to increase evapotran

"Minimum amount of water for irrigation is used" implies efficient water use, which is a sustainable practice.

"Rainfall water harvesting" involves collecting and storing rainwater, reducing reliance on other water sources, making it a sustainable practice.

"Planting crops with broad leaves to increase evapotranspiration" means more water is lost from the plants and soil to the atmosphere. This increases water consumption and is not a sustainable way of using water.

"Growing drought tolerant crops" means selecting crops that require less water, which is a sustainable practice.

The option that is not a sustainable way of using water is C.

The final answer is $\boxed{\text{C}}$
