Every step explained - no skipped algebra.
An oxbow lake is formed when a meandering river cuts through the neck of a large meander, abandoning the curved section. Over time, sediment blocks the abandoned meander from the main river channel, creating a crescent-shaped lake. This process typically occurs in the lower course of rivers where meandering is pronounced.
Final Answer: Option B - A lake formed when a river meander is cut off
