  2. 2-1-4-3
  3. 1-2-3-4
  4. 2-1-3-4

Answer

A meander is a bend in a sinuous watercourse or river. A meander forms when moving water in a stream erodes the outer banks and widens its valley, and the inner part of the river has less energy and deposits silt.

An oxbow lake forms when a river creates a meander, due to the river's eroding the bank. A river delta is a landform that forms from deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water.

The correct option is B.
