A)The Red River valley is geologically young (about 9000 years old)and has not carved a deep valley.

All of these choices contribute to the frequent flooding along the Red River of the North. The young age of the valley means that it has not had time to deepen, resulting in a wide floodplain. The low gradient of the riverbed also slows down the flow of water, making it more susceptible to flooding. Additionally, the winter snowmelt runs into still-frozen parts of the river, causing the water to back up and exacerbating flooding.
