Concept:River capture, also called stream piracy, happens when a stronger river intercepts and diverts the flow of a weaker river, leaving the original valley dry.
Explanation:The diverted river no longer flows through its former valley.
The abandoned, dry valley or notch in the highland is known as a wind gap or air gap.
This dry gap is a clear evidence of river capture.
A delta forms where a river deposits sediment at its mouth.
A meander is a bend in a river's course.
A levee is a natural embankment along a riverbank.
These three features are formed by active river flow, not by capture.
Therefore, the feature directly associated with river capture is the wind gap.
Answer:B. Wind gap
