Mining is defined as

• A. A safe, environmentally friendly way to harvest crops.
• B. The study of ecosystems.
• C. A dangerous practice that involves extracting resources from the Earth.
• D. The process of refining metal ores.

Answer: (C)

Mining is the activity of removing valuable resources from the Earth, such as minerals, ores, metals, or fossil fuels. It focuses on extraction, not on growing crops, studying ecosystems, or refining materials. The reason the statement that mining is a dangerous practice that involves extracting resources fits best is that mining inherently involves subsurface work, heavy machinery, and often hazardous conditions like cave-ins, gas exposure, or chemical risks, which makes it commonly associated with danger. Understanding the alternatives helps: harvesting crops is agriculture, not extraction of minerals; studying ecosystems is ecology, which is about living communities and their environments; refining metal ores is a processing step that occurs after extraction to separate metals from ore, not the act of extracting resources itself.
