A Correct answer
Explanation

Solder is primarily an alloy of lead and tin. The most common solder alloy is 60% tin and 40% lead (60/40 solder) or 63% tin and 37% lead (63/37 solder). This combination has a low melting point, good wetting properties, and strong electrical conductivity, making it ideal for joining electrical components and metal work.
