which area is the best place to mine sandstone?
a. area 1
b. area 2
c. area 3
d. area 4

Explanation:

Sandstone is a sedimentary rock, and limestone (a sedimentary rock too) is represented by the green color in the legend. We need to find the area with the green (limestone - like, as sandstone's presence might correlate with limestone - rich areas or the green - colored region here). Looking at the options, Area 4 (D) is in the green - dominated region which is associated with limestone - type rocks, and sandstone is often found in such sedimentary rock - rich areas.

Answer:

D. Area 4
