In physical geography what is a pass?

Correct answer: Route between mountains

The direct answer is option A: a route between mountains, more precisely a pass is a relatively low route or gap through a mountain range that allows people, roads, or trails to cross from one side to another. The reasoning is simple: mountains create high barriers; a lower opening or saddle provides a usable crossing; that crossing is called a pass. Option A is correct. Option B is an island surrounded by water, not a mountain route. Option C is the river mouth, where a river enters a sea, lake, or another river. Option D is a sandy plain, a landform made largely of sand and not necessarily located between mountains. A pass may be narrow or broad and may be used for transport or communication. In India, mountain passes are important for routes across the Himalayas. Memory cue: pass means a passage through mountains.
