Which of the following best describes a type of welding process listed among the resistance welding types?

Explanation:
Resistance welding relies on heating produced by electrical resistance as current passes through the metal while pressure is applied to form the joint. Spot-and-seam fits this family because it describes welding methods that generate heat through electrical resistance and create welds by pressing the sheets together, either at spots or along a seam. The other options rely on different heating methods: MIG and TIG use an electric arc to melt metal (with or without filler), and oxy-fuel uses a flame to melt metal. So spot-and-seam is the option that aligns with resistance welding.
