Correct Option: D
The correct answer is the oxy-acetylene flame, used for cutting and welding metals.
Oxy-ethylene flame: Possibly a misunderstanding of oxy-acetylene flame; it produces very high temperatures suitable for cutting and welding metals.
Acetylene flame: Standard term for high-temperature flame for metalwork.
Miners' lamp/Hunters' torch: Do not require high temperatures generated by a gas flame mixed with oxygen.
