Which FCAW electrode is a metal cored electrode?

Explanation:
In FCAW, the designation ending with the letter M identifies a metal-cored electrode. The metal core inside the wire adds metallic material and works with the flux around it to boost deposition rate and welding performance. Among the options, the electrode that carries the M suffix is the metal-cored one, making it the correct choice. The other options are not metal-cored FCAW wires: they are either stick (SMAW) electrodes or a stainless steel filler, which do not have a metal-core designation.
