Concept:Metallurgy is the complete process that covers both extracting a metal from its ore and refining it for use.
Explanation:Extraction alone only removes the metal from its ore.
Refining purifies the extracted metal to remove impurities.
Metallurgy combines these two steps into one scientific field.
Option A, "Extraction," describes only part of the process.
Option B, "Metal mining," is the act of digging out the ore from the ground.
Option D, "Prospecting," means searching for mineral deposits.
Therefore, the term that names the whole process of extracting and refining is metallurgy.
Answer:C. Mettallurgy (correctly spelled as Metallurgy)
