What is the path through which a river flows generally called?

Correct answer: River course

The direct answer is D, river course. A river has a source, a course and a mouth. The course is the path or channel followed by the river as it travels from its source toward its mouth. The question asks specifically for the path through which the river flows, so option D gives the most exact answer. A valley is a broader low area between hills or mountains; a river may flow through a valley, but the valley is not the river’s exact path. A coastline is the boundary where land meets the sea, so it does not describe the course of an inland river. An archipelago is a group of islands, not a flowing route. Therefore D is correct. In some geographical descriptions, people may discuss a river valley or channel, but among these four options, river course is the direct and precise term. Memory cue: source to mouth equals the river’s course.
