The image shows a high-elevation, low-relief landform with a river flowing over it. which type of landform is shown? hillmountainplainsplateau

plateau

Explanation:

Let's see the possible answers:

hill : No. A hill is a relatively small and round relief on a normally flat area.  Not the case here... especially since the question mentions a low-relief.

mountain : No.  A mountain is a big relief, much bigger than a hill... with steep sides and a summit...  again, nothing like a low-relief.

plains : No.  Although plains are also flat, they are low-elevation, think about fields for growing crops.  

plateau: Yes.  A plateau is a relatively flat (low-relief) that is significantly elevated compared to its surroundings.  Drops from a plateau is usually the best scenario for a waterfall, like on this picture.
