Final answer:

The most likely locations to find a braided stream are broad, sloping plains next to mountain ranges and flat-bottomed valleys between mountains. A braided river can be discerned from its sedimentary features such as sand deposits and cross-bedding. Typical river features to locate include cut bank, point bar, and levee, among others. The correct option is a.

Step-by-step explanation:

The two most common areas where one would expect to find a braided stream or river are: a) Broad, sloping plains that flank mountain ranges and c) Flat-bottomed valleys between mountains.

These regions typically have variable flows and a significant sediment supply, which can lead to frequent changes in the channel pattern and the formation of temporary islands.

A braided river environment can be identified by features such as sand deposits, sediment beds with layers of gravel, and cross-bedding.

These features suggest a dynamic system with variable water flow and sediment deposition, unlike a swamp or wetlands which would have different characteristics.

Locating and marking features associated with a river system could include a cut bank, point bar, levee, oxbow lake, thalweg, flood plain, and terrace.

Difficulties in completing these tasks could arise from a lack of familiarity with these features or the inability to identify them on a map without clear indicators. The correct option is a.
