What type of landform typically develops between hills and drainage ways?

The correct choice is constructional landforms. Constructional landforms form in areas where there is deposition of sediments, often occurring at the convergence of natural gradients such as between hills and drainage ways. These features can be associated with sediment accumulation that takes place when water flow decreases, allowing sediments carried by runoff to settle in lower-lying areas. This process leads to the development of various types of landforms that can achieve elevation through the build-up of materials.

In contrast, other types of landforms mentioned in the options do not fit this description as closely. Floodplains are flat, low-lying areas adjacent to rivers and streams that are subject to flooding, but they are specifically linked to bodies of water and not necessarily to hills. Valleys are typically elongated low areas that can be carved by erosion from water flow rather than formed through sediment deposition. Plateaus are elevated flatlands that result from geological processes like uplift and volcanic activity, again differing significantly from what develops between hills and drainage ways. The characteristics of constructional landforms, specifically deposition and sediment build-up in transitional areas, make them the most suitable answer for this question.
