The fault is clearly visible as a linear feature running diagonally across the image. On the eastern side of the fault, the mountains appear to be uplifted and tilted, while on the western side, the valleys appear to be lowered. This indicates that the fault is a normal fault, with the eastern side moving up relative to the western side. Therefore, the best choice is B, "east side up."
