Explanation:

A watershed is defined as a land area where all surface water runoff drains into a common point (like a river, lake, or ocean). The correct option matches this definition, while others incorrectly describe it as a river, a dividing ridge (which is a divide), or flowing runoff itself.

A watershed is an area of land that drains runoff into a river.
