Answer: South
Explanation: If you go to the north, the map is telling you with a darker color that the forest is denser up there. Also, the contour lines tell you that it is a mountain because the lines are closer. East and west are not an option because there is water. So, the right answer is south, because the map indicates you with a lighter color that there is less vegetation and also the space between the lines tells you that it is flat or that at least you won't find any mountain.
