Plants are important to the development of karst primarily because
A)openings adjacent to their roots serve as microchannels that allow water to enter the rock.
B)the decay of large roots below the surface produces cavities which eventually enlarge to form caves.
C)they supply organic acids that enhance the dissolution process.
D)they provide the calcium carbonate necessary for karst topography to form.
E)they lessen the impact of raindrops on the surface so the water can more rapidly flow into stream channels.

Question

Plants supply organic acids that can enhance the dissolution process in karst, leading to the formation of sinkholes, caves, and other unique surface features. The acids come from the breakdown of plant material and root respiration.
