Quizplus · Accepted Answer

A lake that a river flows into can act as a local base level because the river cannot erode below the level of the lake. As the water flows into the lake, it slows down and loses energy, which prevents further erosion. The lake serves as a barrier to further downward erosion. The other options (B, C, and D) do not provide such a barrier and do not act as a local base level.
