Based on the image from the Investigation, which terrain is composed of basalt with a few impact craters?

A) Western Terrain W)
B) Dark Terrain D)
C) Sedimentary Terrain S)
D) Polar Ice P)
E) none of these

Basalt is a dark-colored, fine-grained igneous rock, and terrains composed of basalt often appear darker than their surroundings. The presence of a few impact craters suggests a relatively young surface, as older surfaces tend to have more craters due to longer exposure to space debris. Therefore, the "Dark Terrain D" is the correct choice, as it is consistent with the characteristics of basaltic terrain.
