The river in this area has a rather particular pattern, what geologic process caused this? A. a meander eroded through its bank and created an oxbow lake B. the river is in a karst terrain and disappeared into the ground C. the river is following patterns, likely faults, in the underlying bedrock D. during a flood the river breached the natural levee flowing into the floodplain

A. a meander eroded through its bank and created an oxbow lake

Explanation:

A meander is one of the series of the patterns that include the bends and the curves and the loops and windings in the channels of the river and the stream and it swings for the side to the side and flows across the floodplains and is created by the eroded and is formed in the decorative patterns as well by the geomorphic features that result oxbow lakes which are a form of the cutoff lakes.
