What geographic feature is described below? a large, mostly treeless grassland in South America, especially in Argentina

a. highland

b. canal

c. pampas

d. llano

C. pampas

A highland any area of land high in elevation, a canal is a man-made channel of water used for transportation or irrigation, and a llano is a small grassland, not a large one. Incidentally, a, c, and d are also the names of towns in Texas, not that that has any bearing at all on this situation.
