A. Surface mining

B. Placer mining

C. Subsurface mining

D. None of the above

A

Answer: C. Subsurface mining

Subsurface mining is likely to be the least harmful to the environment. It is the extraction of minerals from below the surface without the mine being too noticeable on the surface. It is used in mining minerals like zinc, gold, nickel, diamonds, etc. Digging tunnels into the earth to create a path to reach mineral deposits in the ground is a typical procedure for subsurface mining.
