Answer» B. Gorge
Explanation: Youthful rivers or streams are typically found in the highland or mountainous areas. They are characterized by steep slopes, a relatively small volume of water and rapid flow. Soil particles carried by youthful streams flow along the ground, wearing down hill slopes as the water flows down. In this youthful stage of the river, such features as small lakes, waterfalls, rapids, V-shaped valleys, gorges and interlocking spurs are frequently found.
