Answer to Question 1

C

Answer to Question 2

A floodplain is the flat, low-lying area adjacent to a channel and subject to recurrent flooding. Floodplain contain characteristic depositional landforms. On either bank of some rivers, low ridges of course sediment known as natural levees are formed as byproducts of flooding. On meandering river floodplains, wetlands called riparian marshes are formed by poorly drained sediment. If there is active entrenchment, alluvial terraces may form, etc.
