Answer & Solution
Correct Answer:
Option
C
Solder is a fusible metal alloy used to join together metal workpieces, typically in electronics and plumbing applications.
The most common type of solder is made from a combination of tin (Sn) and lead (Pb).
Tin provides good wettability, allowing the solder to flow easily and bond with the base metals.
Lead lowers the melting point of the alloy, making it easier to melt and apply during soldering.
Typical solder compositions include 60% tin and 40% lead (60/40 solder), or 63% tin and 37% lead (eutectic solder).
Therefore, the correct answer is: Tin and lead.

Originally lead/tin based, typically a eutectic alloy of lead and tin, sometimes containing additional elements to improve its properties, used for sealing joints in plumbing and making electrical connections. This has a low melting point and fairly low strength.
Braze welding: copper and tin alloy are used filler rod material.
