Which describes the science of extracting metals from rocky ore?

A metrology
B metal forging
C metallurgy
D metal working

is it C?

Yes, C

Yes, the correct answer is C. Metallurgy.

To determine the correct answer, you can break down the options and analyze each one:

A) Metrology: Metrology is the scientific study of measurement, but it does not specifically deal with extracting metals from ore.
B) Metal forging: Metal forging refers to the process of shaping metal using localized compressive forces. While this process may involve working with metals, it does not focus on the extraction of metals from ore.
C) Metallurgy: Metallurgy is the branch of science and technology that deals with the extraction, purification, and study of metals from their ores. It involves various processes such as mining, smelting, refining, and alloying.
D) Metal working: Metal working is a broad term that encompasses various processes such as cutting, shaping, and joining metals. While it may involve working with metals that have already been extracted, it does not specifically involve the extraction process itself.

Therefore, the correct answer is C) Metallurgy.

Yes, you are correct. The science of extracting metals from rocky ore is called metallurgy. Therefore, the correct answer is C – metallurgy.
