Arrange the following features formed by rivers in its course starting from upstream:
Select the correct answer using the code given below:
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.
